Where are ATP molecules found?
How many ATP does glycolysis produce?
What is the importance of ATP and Nadph in photosynthesis?
The net effect of these steps is to convert light energy into chemical energy in the form of ATP and NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle.
What is the oxygen of light reaction?
The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.
How is oxygen produced in light reaction?
During the light reaction in photosynthesis, oxygen is released as by product by absorbing light energy by chlorophylls. Source of this oxygen is water. Water splits into hydrogen and hydroxyl ions. The hydroxyl ions released oxygen.
What are the end products of photolysis?
Photolysis is the process by which water is split into oxygen, which is released into the atmosphere, and hydrogen. The hydrogen then becomes bonded to the coenzyme NADP to form NADPH and is transferred to the Calvin Cycle along with ATP.
Where does photolysis occur?
What is the Z scheme?
The “Z‐scheme” describes the oxidation/reduction changes during the light reactions of photosynthesis. Absorption of a photon excites P680 to P680*, which “jumps” to a more actively reducing species. P680* donates its electron to the quinone‐cytochrome bf chain, with proton pumping.
How is P680 different from P700?
P700 is the photo center. P680 is the photo center. The pigments in the photosystem 1 absorb longer wavelengths of light which is 700 nm (P700).
Why is it called P700?
P700, or photosystem I primary donor, is the reaction-center chlorophyll a molecular dimer associated with photosystem I in plants, algae, and cyanobacteria. Its name is derived from the word “pigment”, and the maximal wavelength of light it can absorb, 700 nm, at which the phenomenon of photobleaching would occur.
