STANDARD Zoology Chemiosmotic Hypothesis MCQ Question
Chemiosmotic theory of ATP synthesis in the chloroplasts and mitochondria is based on
Proton gradient
Accumulation of K ions
Accumulation of Na ions
Membrane potential
Correct Answer
Detailed Explanation
Peter Mitchell (1961) proposed the chemiosmotic mechanism of ATP synthesis which states that ATP synthesis occurs due to proton flow H⁺ through a membrane due to proton gradient the protons move to the matrix while passing through proton channel of F₀-F₁ ATPase. This proton gradient activates the enzyme ATP synthases that control the formation of ATP from ADP.
