"WebBased on a lot of experimental work, it appears that four H ^+ + ions must flow back into the matrix through ATP synthase to power the synthesis of one ATP molecule. When electrons from NADH move through the transport chain, about 10 H ^+ + ions are pumped from the matrix to the intermembrane space, so each NADH yields about 2.5 ATP.
