What happens when you combine a split hydrogen atom and a split oxygen atom in the same reaction?

The compound of the atom is largely irrelevant. What is more important is its atmosphere in which they are introduced. If this was done in a vaccum, then nothing. The Electrons, neutrons and protons would pull together into a magnetic field from the atoms and would simply stay together. However, if this was done in a densely populated space, full of other atoms, the result is different. The change of state would be affected by other particles close by, causing an atomic reaction. Nothing like an atom bomb, the energy expanded would be mostly light and high frequency waves such as gamma or infared waves. At least, that is my best guess, physics is not my speciality!

Where does photosynthesis occur in the cell?

Photosynthesis occurs in the chloroplasts of plant cells. Specifically, the light-dependent reactions occur in the thylakoid membranes within the chloroplasts, while the light-independent reactions (Calvin cycle) occur in the stroma of the chloroplasts.

What do ATP synthase molecules do?

That's an easy one. An ATP molecule is an adenosine-derived nucleotide, C10H16N5O13P3, that contains high-energy phosphate bonds and is used to transport energy to cells for biochemical processes, including muscle contraction and enzymatic metabolism, through its hydrolysis to ADP. ATP is hydrolyzed to AMP when it is incorporated into DNA or RNA.

What happen to the sugar that is produced to the leaves?

The sugar that is produced in the leaves through photosynthesis is either used as a source of energy for the plant's growth and metabolism or stored as starch for later use. Some sugars are also transported to other parts of the plant, such as the roots and fruits, to support their growth and development.

Where does photosynthesis takes place?

Chloroplasts of a plant cell

photosynthesis happens in the leaves the chemical equation is water+carbon dioxide->sunlight->oxygen +glucose

Green Leaves

Chloroplasts (in plants).

Photosynthesis occurs in the Chloroplasts which is only found in plants. Chloroplast takes energy from the sun and changes it to chemical energy which is then used by the plant for different functions.

Chemical Equation: Carbon dioxide + water = glucose + oxygen

In chloroplasts

How is the light energy absorbed by plants important to photosynthesis?

Beacuse the light energy is converted into chemical energy (in the form of sucrose and glucose) through photosynthesis; the chemical energy is then utilised by the plant through the process of respiration.

What role do plant pigments play in the process of photosynthesis?

Pigments are able to absorb specific wavelengths of light which power photosynthesis. Chlorophyll, which is green, absorbs all wavelengths except green. Each photon excites an electron in the light harvesting complexes of a photosystem in a chlorophyll molecule, eventually producing ATPs. Other pigments will be a different color and will be able to absorb other wavelengths, maximizing energy absorbency when the sun's rays change.

What are some important facts about arsenic?

  1. Arsenic is a naturally occurring element found in the Earth's crust.
  2. It is highly toxic to humans and can cause both acute and chronic health effects.
  3. Arsenic exposure can occur through contaminated water, food, or air, and is a significant public health concern globally.

What is the name of the molecule that's the source of oxygen produced during photosynthesis?

H2O is the molecule that is the source of oxygen from photosynthesis. It is important to note that the oxygen is a by-product of photosynthesis. Some chemical names for it includes hydrogen hydroxide and dihydrogen monoxide.

What role does chlorophyll play in photosynthesis?

Chlorophyll absorbs light rays. The light rays excite electrons in the chlorophyll and the electrons leave, where they go into the electron transport chain, and make adenosine triphosphate (ATP.) the ATP is used to combine 5 carbons sugars with the carbon from CO2 to make glucose.

Why is EMR important when studying photosynthesis?

EMR (electromagnetic radiation) is important in studying photosynthesis because it provides the energy required for the process to occur. Specifically, the visible light spectrum of EMR is absorbed by chlorophyll in plants, initiating the process of converting light energy into chemical energy. Studying EMR helps understand how different wavelengths of light influence photosynthetic efficiency.

What are the results of respiration?

The results of respiration are the production of energy in the form of ATP, along with the release of carbon dioxide and water as byproducts. Oxygen is also consumed during respiration to help facilitate the breakdown of glucose into energy.

Result of starch test on variegated leaves?

Starch test on variegated leaves may show varying levels of starch accumulation in different parts of the leaves. Green parts of the variegated leaves that contain chlorophyll will likely test positive for starch as they can photosynthesize, while white or yellow parts that lack chlorophyll may test negative or have lower levels of starch. This difference in starch accumulation can indicate the distribution of photosynthetic activity in the variegated leaves.

How do you perform cunninglingus?

To perform cunnilingus, focus on the clitoris with gentle and varying pressure, use your lips and tongue to stimulate the area, communicate with your partner to understand their preferences, and maintain a relaxed and attentive approach throughout.

What things are needed for green plants to make food?

Green plants need sunlight, water, carbon dioxide, and chlorophyll to make their own food through photosynthesis. Sunlight provides energy to convert carbon dioxide and water into glucose, a process facilitated by chlorophyll, which gives plants their green color.

Sugar is converted into carbon dioxide during what process in the body?

Sugar is converted into carbon dioxide during cellular respiration, which is the metabolic process that generates energy (ATP) for cells. This process occurs in the presence of oxygen and involves a series of chemical reactions that break down sugar molecules to release energy, carbon dioxide, and water.

What are the farming practices that increases photosynthesis?

Farming practices such as crop rotation, cover cropping, no-till farming, and precision agriculture can increase photosynthesis. These practices help improve soil health, nutrient availability, and water retention, which can enhance plant growth and ultimately increase photosynthetic activity. Additionally, using organic fertilizers and reducing the use of chemical pesticides can also support healthier plants and higher photosynthesis rates.

Why does a solution of chlorophyll appear red when exposed to white light but the chlorophyll in a plant does not?

Chlorophylls reemit a fraction of the light energy they absorb as fluorescence. Irrespective of the wavelengthof the absorbed light, the emitted fluorescence is always on the long-wavelength side of the lowest energy absorption band, in the red or infrared region of the spectrum.

The fluorescent properties of a particular chlorophyll are functions of the structure of the molecule and its immediate environment. Thus, the fluorescence spectrum of chlorophyll in the living plant is always shifted to longer wavelengths relative to the fluorescence spectrum of a solution of the same pigment. This red shift is characteristic of aggregatechlorophyll.

How is photosynthesis effected by winter?

Typically, in winter there is less sunlight. The light that does reach the plants is weaker as the Earth is tilted further away from the Sun in winter. Plants are unabe to photosynthesize without sunlight, it is the power behind the entire process. Also, plants are unable to photosynthesize without water. In the depths of winter, much of this may be locked up as ice and therefore unaccessible to most plants.

How does the process of photosynthesis change during a full day?

During the day, photosynthesis in plants increases as they receive sunlight for energy. The process involves capturing light energy to convert carbon dioxide and water into glucose, releasing oxygen as a byproduct. As the sun sets, photosynthesis slows down due to the lack of sunlight and plants respire to continue producing energy.

Does chlorophyll a absorb mostly orange-red and violet blue light?

actually plants are green to the human eye because they reflect green light witch in return your eyes absorb so the chlorophyll absorbs the red and the blue while reflecting the green spectrum. btw the plants absorb more blue light than red as blue light contains more energy than red due to the higher Frequency and therefor more energy.

What does selectively permeable mean?

Selective permeability refers to the property of a membrane that allows certain molecules or ions to pass through while restricting the passage of others. This selectivity is based on factors like size, charge, and solubility. Essentially, the membrane is capable of regulating the passage of substances based on specific criteria.

How many grams of CO2 in the photosynthesis reaction are required to make 120 grams of glucose?

In the process of photosynthesis, the overall reaction involves 6 molecules of CO2 producing 1 molecule of glucose. The molar mass of CO2 is 44 g/mol and the molar mass of glucose is 180 g/mol. To produce 180 grams of glucose, you would need 6 * 44 = 264 grams of CO2.

What pigments do plants us to carry out photosynthesis?

Plants primarily use two pigments for photosynthesis: chlorophyll a and chlorophyll b. These pigments are located in the chloroplasts of plant cells and absorb light energy to drive the photosynthetic process. Chlorophyll gives plants their green color and is essential for capturing sunlight for energy conversion.

What are the reactants in photosynthesis?

The reactants in photosynthesis are carbon dioxide and water.

The overall reaction of photosynthesis is:

carbon dioxide + water --> glucose + oxygen gas + water

(some diagrams include the energy provided by light, but this is not a true reactant)

The catalyst, which is mostly recycled, is chlorophyll.
