Question

Quizplus · Accepted Answer

The Electron Transport Chain (ETC) occurs across the inner mitochondrial membrane, where it uses electrons from NADH and FADH2 to pump protons out of the mitochondrial matrix, creating a proton gradient that drives ATP synthesis. Glycolysis occurs in the cytoplasm, and the Krebs cycle takes place in the mitochondrial matrix, not across the membrane.
