Photosynthesis - Photosynthesis - The pathway of electrons: The general features of a widely accepted mechanism for photoelectron transfer, in which two light reactions (light reaction I and light reaction II) occur during the transfer of electrons from water to carbon dioxide, were proposed by Robert Hill and Fay Bendall in 1960. What is the formula for Actual Size and Magnification? ADP + NADP + H2O → ATP +NADPH + H ion + O2 The reason why this stage is called “Light Reaction” is because light plays a big part of the reaction, enzymes are also required to catalyse them.

NADP + is the common notation for the nonreduced form, and NADPH is the name once it has been reduced, or gained an electron. The role of NADPH is mostly anabolic reactions, where NADPH is needed as a reducing agent, the role of NADH is mostly in catabolic reactions, where NAD + is needed as a oxidizing agent. Along with electron that come from the acceptor of electrons of PSI protons are necessary for the reduction of NADP + to NADPH + H +.These protons are also removed from the stroma.
