Sorry, no etymologies found.
'photophosphorylation' and 'oxidative phosphorylation', respectively.
This theory provides a rational basis for future work on the detailed mechanisms of oxidative phosphorylation and photophosphorylation.
The above concepts had been broadly outlined by about the beginning of the 1960s, but the exact mechanisms by which electron transfer is coupled to ATP synthesis in oxidative phosphorylation and in photophosphorylation remained unknown.
In higher cells, photophosphorylation and oxidative phosphorylation occur in specific membrane-enclosed organelles, chloroplasts and mitochondria, respectively; in bacteria, both these processes are associated with the cell membrane.
Organisms form the kingdom Plantae usually use noncyclic (do not reCYCLE same electrons) photophosphorylation, a two-stage process involving two different chlorophyll photosystems.
Slide 20: Photochemistry Bio-Nano Energy In cyclic photophosphorylation electrons from ferredoxin (Fd) are shuttled into the cytochrome b6f complex which then pumps protons out of the stroma into the thylakoid lumen.
