DENDROLOGY

Detailed explanation-1: -ATP and NADPH are energy storage and electron carrier/donor molecule. Both ATP and NADPH are used in the next stage of photosynthesis. The chlorophyll molecule regains the lost electron from a water molecule through a process called photolysis, which releases dioxygen (O2) molecule.

Detailed explanation-2: -Electron flow between the photosynthetic complexes is mediated by two mobile carriers, plastoquinone and plastocyanin in the lipid bilayer and lumenal space, respectively.

Detailed explanation-3: -NADPH is a mobile electron carrier. In photosynthesis, its function is to transport two electrons and a proton from the Light Dependent Reactions to the Calvin Cycle.

Detailed explanation-4: -The final electron acceptor is NADP+, which is reduced to NADPH. NADPH generated from light reactions is used in sugar synthesis in dark reactions. Light reactions also generate a proton motive force across the thylakoid membrane, and the proton gradient is used to synthesize ATP.

Detailed explanation-5: -ATP and NADPH are two types of protein carriers.
