The direct formation of ATP by the transfer of a phosphate group from a donor molecule to ADP is called ________.
a. substrate-level phosphorylation
b. oxidative phosphorylation
c. cyclic photophosphorylation
d. noncyclic photophosphorylation
e. indigenous phosphorylation
Oxidative phosphorylation is a two-stage process where ATP synthase couples the electron transport chain to ATP synthesis. In the first part, energy stored in reduced electron carriers is extracted via a series of redox reactions to drive ADP phosphorylation in the second stage, known as chemiosmosis.
