Oxidative phosphorylation is
Options
- AFormation of ATP by transfer of phosphate group from a substrate to ADP
- BOxidation of phosphate group in ATP
- CAddition of phosphate group to ATP
- DFormation of ATP by energy released from electrons removed during substrate oxidation
Correct answer
D. Formation of ATP by energy released from electrons removed during substrate oxidation
Step-by-step solution
Oxidative phosphorylation uses the energy of oxidation-reduction of a substrate to generate ATP. Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
