Electron transfer chain

... ETC is used to power membrane transporters and adenosine triphosphate synthesis by ATP synthase (aka the F 0 F 1 particle). They are used in photophosphorylation and respiration . In eukaryotes , including humans, an ETC is found spanning the inner mitochondrial membrane and accepts electrons from ...

Photosynthesis

... two electrons , which are transferred along an electron transport chain , similar to that involved in respiration. Their energy is used for photophosphorylation , which produces adenosine triphosphate (ATP), the main "energy currency" in cells. In photosystem I, the electrons are returned to the ...

Phosphorylation

... . ATP is also synthesized by substrate level phosphorylation during glycolysis . ATP is synthesized at the expense of solar energy by photophosphorylation in the chloroplasts of plant cells. Phosphorylation of sugars is often the stage of their catabolism . It allows cells to accumulate sugars ...
