Vedclass · Answer

(D) During the process of oxidative phosphorylation in mitochondria,the electron transport system $(ETS)$ is located in the inner mitochondrial membrane.As electrons pass through the complexes of the $ETS$,energy is released and used to pump protons $(H^+)$ from the mitochondrial matrix into the intermembrane space.This creates a high concentration of protons in the intermembrane space,establishing a proton gradient (electrochemical gradient) across the inner mitochondrial membrane.This gradient drives the synthesis of $ATP$ through the enzyme $ATP$ synthase.
