What does oxidative phosphorylation include?

Members don't see this ad.

Does it include both electron transport and chemiosmosis or just chemiosmosis （the process of proton flowing back)？

 

[shyfox9p]

I believe its both

 

[emminent]

Both; cheiosmosis is more specific whereas ETC is the whole thing.

 

[biomolecmed]

Both. Definitely the entire ETC.

Oxidative phosphorylation is when ATP is produced from adding a phosphate group to ADP in which the energy for the bond and the phosphate group are obtained from separate sources (same source such as glucose in glycolysis [yielding 2 ATP] is substrate level phosphorylation).

So yes both are examples of oxidative phosphorylation since the energy for the bond is derived from ATP synthase and the phosphate group is obtained from the mitochondrion matrix.
