Figure 1: A schematic diagram of the electron-proton transport chain of oxygenic photosynthesis. Both PSI and PSII are multisubunit pigment protein complexes embedded in the thylakoid membrane of ...

So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that maintain life, said Donald Canfield, a geobiologist at the University of ...

Central to BPV systems is the process of extracellular electron transfer (EET), where electrons generated during photosynthesis ... can alter the electron transport chain independently of EET ...
