mitochondrial matrix.

intermembrane space. (correct)

cytosol.

electron-transport chain.

NADH dehydrogenase complex Signup and view all the answers

In oxidative phosphorylation in mitochondria, high-energy electrons are transferred to the electron-transport chain from activated carriers like NADH. Stage 1 of photosynthesis also uses an electron-transport chain to pump protons and make ATP. In this case, where do the high-energy electrons come from?
