Who discovered photosynthesis?

Jan Baptista van Helmont, a Flemish chemist, physiologist, and physician, discovered the beginnings of photosynthesis.

He performed a biological experiment on a willow tree in 1643. He carefully measured the mass of the soil used by a plant and the mass of the plant as it grew. After noticing that the soil mass changed very little, he hypothesized that the mass of the growing plant must come from the water, the only substance he added to the potted plant.

Although some of the steps in photosynthesis are still not completely understood, the overall photosynthetic equation has been known since the 19th century.

What factors can influence the mip rate of measuring performance?

Factors that can influence the MIP rate of measuring performance include the level of data accuracy, the appropriateness of key performance indicators (KPIs), the frequency of data collection and reporting, and the alignment of organizational goals with performance metrics. Additionally, the use of technology for data collection and analysis can also impact the MIP rate.

How does cellular respiration work?

Cellular respiration occurs when there is oxygen

Oxygen+Glucose=Carbon dioxide, water and ATP

The purpose of cell. resp. is to produce ATP for cellular work

The first step of cellular respiration is called GLYCOLYSIS

Glycolysis occurs in the cytoplasm. The glucose molecule is split in this stage to make 4 ATP molecules 2 ATP molecules go to starting the next step so a net of 2 ATP molecules are made by Glycolysis

The next step is called the Krebs cycle

Krebs Cycle occurs in the matrix of the mitochondria. In this stage some complex stuff happens so I suggest you ask the internet(it's open all night). For High School Honors Biology all you need to know is that it produces 2 ATP molecules and occurs in the matrix.

The final procedure is called ETC

The electron transport chain occurs in the inner membrane of the mitochondria. Basically H+ ions are transferred to more powerful receptors. This produces 24 ATP molecules. Overall, approximately 28 ATP molecules are produced( this is a debated topic)

What is sugar made out of?

Sugar cane is a type of plant that is grown and then harvested into sugar.

Sugar cane is a sub-tropical crop of tall plants with very thick stems. The stems are harvested and they are crushed in order to extract the sweet juice. The juice is purified and the water content is boiled off. Eventually the process reaches a stage when sugar crystals grow. The results are a brown raw sugar that resembles the sweet brown sugar used to make baked goods.

How does photosynthesis affect global warming?

Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.

During photosynthesis what happens to energy?

During photosynthesis, energy from sunlight is captured by chlorophyll molecules in plant cells. This energy is then used to convert carbon dioxide and water into glucose (a form of chemical energy) and oxygen. The glucose can be used by the plant for energy or stored for later use.

What is combined with two oxygen atoms and helps plants engage in photosynthesis?

Carbon dioxide is combined with two oxygen atoms to help plants engage in photosynthesis. During this process, plants take in carbon dioxide from the air and convert it into sugars and oxygen with the help of sunlight.

Where does electron transport in photosynthesis take place?

Electron transport in photosynthesis takes place in the thylakoid membrane of the chloroplast. It involves a series of protein complexes that transfer electrons along a chain, creating a proton gradient that drives ATP synthesis and ultimately produces NADPH for the Calvin cycle.

Differentiate aerobic and anaerobic respiration?

Hi, For this answer, i am assuming you have some high school biology knowledge (general understanding of glycolysis, kreb cycle, pyruvate oxidation etc..) Anaerobic respriation and fermentation differ in the chemical pathways. Fermentation occurs when the pyruvate (or some derivative of it) that is produced after glycolysis is reduced by NADH to usually form an organic compound (lactic acid in lactic acid fermentation and ethanol in alcoholic fermentation). It is important to note that fermentation does not have to occur in anaerobic evironments, for example yeast prefers fermentation even in the presence of oxygen (as long as sugars are available). Therefore, the defining characteristic of fermentation is that the electrons from the coenzymes (NADH from the glycolosis) are transfered back to part of the original substrate (pyruvate). Note that the electrons are donated to something which came from within the cell (pyruvate). On the other hand, anaerobic respiration is actually very similar to aerobic respiration. In anaerobic respiration, you would go through glycolysis, pyruvate oxidation, kreb cycle and then electron transfer chain just as you would in aerobic respiration with the difference that that the terminal electron acceptor is NOT oxgyen (nitrate, nitrite etc..). The defining characteristic here is that the terminal electron acceptor is anything by oxygen but otherwise, it is very similar to aerobic respiration. Note that the electrons are donated to something which came from outside the cell (nitrate, nitrite etc..). Therefore, fermentation goes something like glycolysis -> donating electron back to pyruvate or a derivative of pyruvate (electron acceptor from internal source); while anaerobic respiration goes something like glycolysis -> pyruvate oxidation -> kreb cycle -> electron transfer chain with terminal electron acceptor being anything but oxygen (electron acceptor from external source). Hope this made sense

What does 'like oil on water' mean?

The phrase "like oil on water" is often used to describe something that doesn't mix well or interact harmoniously with something else, highlighting a sense of separation or difference. It signifies a lack of integration or compatibility, much like how oil and water do not blend together.

What does photo shot under incandescent lights to look slightly warm mean?

By warmer, they mean that the color leans toward yellow and orange. Daylight film (or a digital camera set to daylight) are balanced so that light such as you see outdoors or through a window will appear natural or white. This is the wonderful thing about digital: between frames, you can switch the color balance to incandescent (tungsten) so an image taken near an incandescent lamp will appear less yellow. If you shoot raw, then the color balance is not affected until later in your editor.

To demonstrate this, you can take a picture of a person with one side facing a window and the other side facing a table lamp (with a regular bulb - not fluorescent). Shoot one picture with the camera set to daylight and one picture with the camera set to incandescent/tungsten. Then compare. You can take the same shots and play with the color balance in program like Photoshop. There are good examples in books and magazines, but it's good to do it yourself so you know your camera settings.

Watch out for fluorescent bulbs and the kind of lights like you see in gymnasiums. To the human eye, they appear fairly white, but they are changing color and brightness (flickering) at 60 times a second. So you want a shutter speed that is 1/60 or longer to avoid problems. Even then, they aren't really quite white. Most digital cameras have a fluorescent setting to take care of the difference. Some films handle this better than others.

How do jellyfish get oxygen out of their environment for respiration?

Its because their skin is so thin on the body and tenticles that the oxygen flows through their body and goes through to its vital organs, carbon dioxide is removed the same way. They breathe with their entire bodies.

How would you describe the Calvin cycle?

C02 + ribulose biphosphate ------>(catalyst by riubisco) -----> 6C compound(unstable) -----> glycerate-3-phosphate ---->(ATP->ADP+P)---->(NADPH->NADP + H)----> trise phosphate ----->sucrose

Water participates directly in the light reactions of photosynthesis by?

Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.

What functional group is different in the identical pigments of chlorophyll a and chlorophyll b?

The functional group that differs between chlorophyll a and chlorophyll b is the aldehyde group on chlorophyll b, which replaces the methyl group on chlorophyll a at the C7 position of the chlorophyll molecules.

What are the raw materials and the products of photosynthesis?

Photosynthesis is the process when plants use energy from the sunlight to produce glucose from carbon dioxide and water. Carbon dioxide, water and sunlight are the raw materials of photosynthesis. Oxygen and glucose are the products.

The raw materials are carbon dioxide (CO2) and water (H2O); the process of photosynthesis is a complex series of chemical reactions resulting in the production of glucoseand oxygen (O2). Glucose is a simple sugar, which is further processed into fructose and sucrose, and any sugars not required immediately to be metabolized for their energy are converted into starches: complex carbohydrates used to store these essential sources of energy for when they are required. The process of photosynthesis is summarized in a series of reactions called the Calvin Cycle; and you can find this process summarized in relatively simple steps, or described in it's full complexity down to the movement of every electron. The organ of photosynthesis in the plant cell is the CHLOROPLAST.

What is the word equation for aerobic respiration?

The balanced equation:

C6H12O6 + 6O2 --> 6H2O + 6CO2 + energy The most basic, unbalanced equation is:

C6H12O6 + O2 --> H2O + CO2

Why is respiration essential for life?

Respiration is not essential for life. Many forms of bacteria do not undergo cellular respiration and are still considered 'alive'. Respiration, more specificially cellular respiration, is just one of many ways (although one of the more energetically efficient ways) for a cell to produce energy.

Human cells are capable of producing energy in one of two ways, depending on the condition the cells are placed in. The most common of the two ways is through cellular respiration. This occurs when there is sufficient oxygen being carried to the cells via the blood. The second occurs when the body's cells do not have enough oxygen to support cellular respiration. This is commonly experienced during heavy workouts. When the body's cells don't have the needed oxygen to undergo cellular respiration, the cells revert to a form of energy creation called 'fermentation,' which DOES NOT require oxygen. Fermentation causes the build-up of lactic acid in muscle cells, which leaves that sore feeling in your muscles after a workout.

What kinds of chemical reations occur inside the body?

Literally there are hundreds of billions of chemical reactions which take place in the human body per second alone. These include how we make heat and energy through respiration of oxygen (O2) and glucose (C6H12O6). There is also how this reaction produces the waste of CO2, and how the blood carries it as carbonic acid to be expelled by the lungs.

How are photosynthesis and cellular respiration different?

Photosynthesis:

  • occurs in plants and some bacteria.
  • only occurs in the presence of sunlight/UV light
  • occurs within the chloroplasts.
  • requires chlorophyll
  • uses water, light energy and carbon dioxide
  • produces oxygen and glucose (which are the reactants of cellular respiration)
  • captures light energy to store as chemical energy
  • builds up the plant's energy stores
  • chemical formula is 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2
  • is an anabolic reaction, i.e. simple molecules are built up into complex ones
  • occurs in two phases: the light and dark reactions
  • uses NADP to carry hydrogen ions
  • is an endothermic process
  • results in the production of carbohydrates
  • captures light energy and converts it to chemical energy
  • energy is solar energy converted to chemical energy

Cellular Respiration

  • occurs in plants and animals.
  • occurs at all times in all living organisms
  • occurs within the cytoplasm and mitochondria.
  • does not require chlorophyll
  • uses oxygen and glucose
  • produces energy (in the form of ATP), carbon dioxide, and water (which are the reactants of photosynthesis)
  • chemical formula is C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy (ATP)
  • is a catabolic reaction, i.e. complex molecules are broken down to simpler ones
  • occurs in three phases: glycolysis, Krebs and the ETS
  • uses NAD+ to carry hydrogen ions
  • Is an exothermic process.
  • Involves the use/consumption of carbohydrates
  • takes the chemical energy resulting from photosynthesis and breaks it down, releasing energy
  • energy is the stored chemical energy that originated from photosynthesis; this chemical energy is converted to other kinds of energy like heat and motion (energy required for cellular processes to occur.)

What are the links between the energy that carnivors get from eating to the energy captured by photosynthesis?

These links are called food chains. The herbivors eat plants to get energy taped by plants during photosynthesis. The herbivors are eaten by carnivors to recycle that very energy of photosynthesis. Thus there is a link among producers (plants) and consumers (animals).
