Vedclass · Answer

(C) The chemiosmotic coupling hypothesis,proposed by Peter Mitchell,explains that $ATP$ synthesis in mitochondria occurs due to the electrochemical gradient of protons ($H^+$ ions).$1$. During the electron transport chain,protons are pumped from the mitochondrial matrix into the intermembrane space.$2$. This creates a high concentration of protons in the intermembrane space compared to the matrix,establishing a proton gradient (or proton-motive force) across the inner mitochondrial membrane.$3$. Protons flow back into the matrix through the $F_0-F_1$ $ATP$ synthase complex.$4$. This flow of protons provides the energy required for the phosphorylation of $ADP$ to form $ATP$.

According to the chemiosmotic coupling hypothesis,$ATP$ is synthesized in oxidative phosphorylation because:
