Chemiosmotic theory of ATP synthesis in the mitochondrion is based on

  1. A \(Ca ^{++}\)gradient
  2. B \(K ^{+}\)gradient
  3. C \(H ^{+}\)gradient
  4. D \(Na ^{+}\)gradient
Verified Solution

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.
