Question

Short /Long answer type question.
What is the Z-scheme of photosynthesis ? What are the products of photoreaction and how they are used in the process of $C{O}_2$ fixation ?

Answer 1

The “Z‐scheme” describes the oxidation/reduction changes during the light reactions of photosynthesis. In the Z‐scheme, electrons are removed from water (to the left) and then donated to the lower (non‐excited) oxidized form of P680. An ATP synthase enzyme uses that chemiosmotic potential to make ATP during photophosphorylation, whereas NADPH is a product of the terminal redox reaction in the Z-scheme.
