What is the name of the electron (hydrogen) carrier used in photosynthesis?Where does this carrier \"pick up\" its electrons?

Solution

The photosynthesis process in chloroplasts begins when an electron of P680 of PSII attains a higher energy level. This energy is used to reduce of a chain of electron acceptor. This chain of electron acceptor is known as an electron transport chain. When this chain reaches PSI , an electron is again excited, creating a high redox potential. The electron transport chain of photosynthesis form Z like structure called Z scheme.

The final product of PSII is plastoquinol , a mobile electron carrier in membrane. This transfer electron from PSII to the proton pump cytochrome b6f.

Cytochrome b6f proceeds the electron chain to PSI through plastocyanin molecule. PSI transfer the electron either to plastoquinol again, creating a cyclic electron flow, or to an enzyme calked FNA ( Ferredoxin - NADP + reductase ), creating a non cyclic electron flow. PSI releases FNR into the stroma where it reduces NADP+ to NADPH.
