The process of ATP synthesis in chloroplasts is referred to as
A) oxidative phosphorylation.
B) photophosphorylation
C) reductive phosphorylation
D) substrate-level phosphorylation.

Question

Quizplus · Accepted Answer

The process of ATP synthesis in chloroplasts is referred to as photophosphorylation. This is because it involves the use of light energy to generate a proton gradient across the thylakoid membrane, which is then used to drive the synthesis of ATP through the action of ATP synthase. Option A (oxidative phosphorylation) typically refers to ATP synthesis in mitochondria, while option C (reductive phosphorylation) involves the use of reducing equivalents such as NADH to drive ATP synthesis. Option D (substrate-level phosphorylation) generally refers to the direct transfer of a phosphate group from a substrate molecule to ADP to form ATP, which is not the process of ATP synthesis that occurs in chloroplasts.
