Which one of the following is not true regarding the release of energy during ATP synthesis through chemiosmosis? It involves :

Options

  1. ABreakdown of electron gradient
  2. BMovement of protons across the membrane to the stroma
  3. CReduction of NADP to NADPH 2 on the stroma side of the membrane
  4. DBreakdown of proton gradient

Correct answer

A. Breakdown of electron gradient

Step-by-step solution

An electron transport chain (ETC) is a series of compounds that couples electron transfer with the transfer of protons across a membrane and transfer electrons from electron donors to electron acceptors with the help of redox reactions. This generates chemical energy in the form of adenosine triphosphate (ATP) by creating an electrochemical proton gradient, that drives ATP synthesis. The breakdown of proton gradient along the concentration gradient forms the ATP molecules. F 0 protein complex of ATP synthase forms
