Describe the two stages of photosynthesis?
1. energy captured from sunlight by chlorophyll molecules found in thylakoids.
2. light energy converted into chemical energy: stored in ATP and NADH.
3. chemical energy stored in ATP and NADH powers formation of glucose.
overall photosynthesis equation:
6CO2+ light energy ---> C6H12O6 + 6O2
What are two raw materials for photosethesis?
Two raw materials for photosynthesis are carbon dioxide (CO2) and water (H2O). Carbon dioxide is absorbed from the atmosphere through tiny pores in plant leaves called stomata, while water is absorbed from the soil through the plant's roots.
You need to be smart enough to right a GOOD question. The one you wrote is not a very good one.
And before you criticize anyone on their grammar, you should check your own and learn the difference between right and write...
Is water produced during photosynthesis?
No, water is not produced.Water is broken down to get electrons.
What types of cells go through photosynthesis?
Plants, algae, and some bacteria are the primary types of cells that go through photosynthesis. These cells contain chlorophyll, a pigment that captures sunlight and helps convert carbon dioxide and water into glucose and oxygen through a series of chemical reactions.
NADPH is formed when the electrons acceptor NAPD combines with what?
NADPH is formed when the electron acceptor NADP+ combines with electrons and a hydrogen ion (H+). This reduction reaction takes place during the light reactions of photosynthesis, where energy from sunlight is used to drive the electron transport chain and ultimately produce NADPH.
Describe the connections between the processes of photosynthesis and combustion?
Nobody here is able to see a diagram above, and we're
beginning to wonder whether there really IS one there.
What happens to the products in photosynthesis?
The products of Photosynthesis are :
1) Glucose
2) NADP+, ADP & P
1) Glucose is either used for respiration or stored in the plant in the form of Starch.
2) NADP+, ADP & P return to the Light Dependant stage for another cycle of photosynthesis.
What is photosynthesis products?
The products of photosynthesis are glucose (a type of sugar) and oxygen. Glucose is used by the plant as energy for growth and maintenance, while oxygen is released into the atmosphere as a byproduct.
What does the Calvin Cycle of Photosynthesis require?
The Calvin Cycle of photosynthesis requires ATP (adenosine triphosphate) for energy and NADPH for reducing power, which are produced during the light-dependent reactions of photosynthesis. Additionally, carbon dioxide from the atmosphere is also required for the Calvin Cycle to produce glucose.
Photophosphorylation is most similar to?
Photophosphorylation is most similar to oxidative phosphorylation in that it involves the production of ATP through a series of redox reactions that generate a proton gradient across a membrane. However, in photophosphorylation, the energy for driving the process is derived from light instead of the oxidation of organic molecules.
What is the ultimate electron acceptor in photosynthesis?
The ultimate electron acceptor in photosynthesis is NADP+ (nicotinamide adenine dinucleotide phosphate). It is reduced to NADPH during the light-dependent reactions of photosynthesis and carries electrons to the Calvin cycle for carbon fixation.
What type of cells carry out photosynthesis?
In a leaf photosynthesis takes place in the mesophyll (middle leaf), mostly in the upper layer of palisade cells but also in the spongy layer.
The plant cells don't actually carry out photosynthesis - it takes place in the Chloroplasts.
Extra Credit
Chloroplasts maintain a lot of similarities with photosynthetic bacteria, including a circular chromosome and prokaryotic ribosomes. This has lead to the endosymbiotic theory that suggests that photosynthetic bacteria were acquired by primeval eukaryotic cells which went on to become plant cells.
When a plant cell divides, it's Chloroplasts divide taking their unique DNA along with them, Mitochondria behave in a similar fashion.
What happens to the sugar that is produced by photosynthesis?
The sugar produced by photosynthesis is used as an energy source for the plant to carry out its various functions, such as growth, maintenance, and reproduction. It can also be stored in different parts of the plant, such as the roots, stems, or leaves, as starch for future use. Additionally, some of the sugar may be used to produce other compounds needed by the plant for various metabolic processes.
Which name is given to the region where photosynthesis can occur?
The region where photosynthesis can occur is known as the chloroplasts in plant cells. This is where the pigment chlorophyll captures light energy and converts it into chemical energy to drive the process of photosynthesis.
What are the two reactants needed for photosynthesis?
The raw materials are water, carbon dioxide, sunlight, and chlorophyll.
How does photosynthesis provide food for plants?
Photosynthesis is the process by which the plant takes in Carbon Dioxide, Water and Light from the sun, and creates glucose and oxygen. This occurs in the chloroplasts.
Represented as a chemical equation:
light
C02 + H20 -----> C6H12O6 + O2
Balanced, that would be:
light
6C02 + 6H20 -----> C6H12O6 + 6O2
Glucose is then stored in the cell until needed. During respiration, the mitochondria in the cells breaks down the glucose in a series of chemical reactions. The end result is ATP, which is used as a source of Chemical_energyaround the cell.
So basically, photosynthesis creates organic compounds from inorganic materials, which are broken down through respiration to create energy for the cell.
What structure that is found in the thylakoid membrane is important to chemiosmosis?
ATP synthase is the structure found in the thylakoid membrane that is important for chemiosmosis. It is responsible for generating ATP by utilizing the proton gradient created during the photosynthetic electron transport chain.
What do chloroplast need to perform photosynthesis?
Chloroplasts need light energy, water, and carbon dioxide to perform photosynthesis. Light energy is absorbed by chlorophyll to drive the chemical reactions that convert water and carbon dioxide into glucose and oxygen.
How chlorophyll traps sunlight and converts it to chemical energy?
First of all, chloroplasts are what convert the sun into ATP, which is the basic universal form of energy.Chloroplasts are able to capture solar energy to perform photosynthesis, the reduction of carbon dioxide to simple carbohydrates.They contain chlorophyll to allow photosynthesis to occur.Light absorbed by Chlorophyll excites the electrons. Different wavelengths of light excite the electrons by different amounts.
The energy in the 'excited electrons' can be passed from one chlorophyll molecule to another, but in the end it will just be lost as fluorescence (ie the energy will be re-emitted as light), unless the excited electron itself can be ejected from the chlorophyll molecule.This process of electron ejection takes place only in chlorophyll molecules which are specifically held in a special protein complex called a reaction centre.
There are two different sorts of reaction centres in plants. In each of these reaction centres, the ejected electron is transferred to an acceptor molecule, which can then pass it on to a different molecule and eventually the electron(s) can be used to fix carbon dioxide. However, you can't keep on ejecting electrons from these special chlorophyll molecules, electrons must be fed back in to replace those ejected. These electrons come from water, resulting in oxygen being evolved.
So, basically, solar energy excites electrons which bind molecules into useable substances. (ie ATP)

Substance produced by the mint plant in Joseph priestley's experiment?
Oxygen gas was the substance produced by the mint plant in Joseph Priestley's experiment. This discovery led to the understanding of plants releasing oxygen through the process of photosynthesis.
Is temperature a limiting factor for photosynthesis?
Temperature occurs no matter what the size shape or color of the population is, just like hurricanes, wildfires, and earthquakes therefore it is a density-INDEPENDANT limiting factor. Over
Do crinoids do photosynthesis?
No, they don't. Photosynthesis occurs in the chlorophyll of plants.. Crinoids are animals; do be specific, they are enchinoderms. They are closely related to starfish.
Hope this helped!

What materials are needed for light dependent reaction?
For the light-dependent reactions of photosynthesis, materials needed include sunlight, water, chlorophyll, and other pigments, as well as enzymes and other proteins involved in the electron transport chain and ATP synthase. These reactions take place in the thylakoid membranes of chloroplasts.
