Chemiosmotic theory of ATP synthesis in the mitochondrion is based on
- A \(Ca ^{++}\)gradient
- B \(K ^{+}\)gradient
- C \(H ^{+}\)gradient
- D \(Na ^{+}\)gradient
Answer & Solution
Correct Answer
(C) \(H ^{+}\)gradient
Step-by-step Solution
Detailed explanation
(C) \(H ^{+}\)gradient,
The chemiosmotic theory of ATP synthesis in chloroplasts (photophosphorylation) is based on the proton \(\left( H ^{+}\right)\) gradient. In chloroplasts, this gradient is generated across the thylakoid membrane during light-dependent reactions, driving ATP synthesis through ATP synthase.
