  3. Caccumulation of Na ions
  4. Dmembrane potential

Correct answer

A. proton gradient

Step-by-step solution

Chemiosmotic hypothesis for oxidative phosphorylation (ATP synthesis) was proposed by Peter Mitchell in 1961 for this he was awarded Noble Prize in 1978. This theory is based on proton gradient.
