Vedclass · Answer

(A) The chemiosmotic theory,proposed by Peter Mitchell,explains that $ATP$ synthesis is driven by the flow of protons ($H^+$ ions) across a membrane.In mitochondria,the electron transport chain pumps protons from the matrix into the intermembrane space,creating a proton gradient (electrochemical gradient) across the inner mitochondrial membrane.This gradient represents stored potential energy.Protons flow back into the matrix through the $ATP$ synthase enzyme complex.This flow of protons provides the energy required for the phosphorylation of $ADP$ to form $ATP$.

The chemiosmotic theory of oxidative phosphorylation suggests that adenosine triphosphate $(ATP)$ is produced because:
