Chemiosmotic theory of ATP synthesis in the chloroplasts and mitochondria is based on:
Options
- AProton gradient
- BAccumulation of K + ions
- CAccumulation of Na 2+ ions
- DMembrane potential
Correct answer
A. Proton gradient
Step-by-step solution
Chemiosmotic theory of ATP synthesis in the chloroplasts and mitochondria is based on proton gradient. Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis.
