Background
Figure 1. Photosynthetic electron transport. Light excitation of photosystem II (PSII) and photosystem I (PSI) results in electron transport through protein complexes in the thylakoid membrane. This drives proton pumping, resulting in a gradient that can be harvested for the synthesis of ATP. Ferredoxin (Fd) and Fd:NADP(H) oxidoreductase are at the pivotal point in either distributing electrons to metabolic pahways or returning them to the chain in a cyclic electron flow.
