Answer: 3. formation of ATP by energy released from electrons removed during substrate oxidation

Oxidative phosphorylation is the formation of ATP using the energy released when electrons are passed along the electron transport chain from reduced NADH and FADH₂ to oxygen, in the mitochondria.

Option 4 describes substrate-level phosphorylation.
