Question

7. Oxidative phosphorylation is
(a) formation of ATP by transfer of phosh.
group from a substrate to ADP
(b) oxidation of phosphate group in ATP
(c) addition of phosphate group to ATP
(d) formation of ATP by energy released from
electrons removed during substrate
oxidation

8. The chemiosmotic coupling hypothesis of
oxidative phosphorylation proposes that
adenosine triphosphate (ATP) is formed because
(a) a proton gradient forms across the inner
mitochondrial membrane
(b) there is a change in the permeability of the
inner mitochondrial membrane towards
adenosine diphosphate (ADP)
(c) high energy bonds are formed in
mitochondrial proteins
(d) ADP is pumped out of the matrix into the
intermembrane space.​

Answer 1

Answer:

7.D

Explanation:

Oxidative phosphorylation is a biochemical process in cells. It is the final metabolic pathway of cellular respiration, after glycolysis and the citric acid cycle. 26 of the total 30 ATP (energy carrier) molecules generated from a single glucose molecule during cellular respiration come from oxidative phosphorylation.
