ANSWER:Step 1 of 3
Within the mitochondria, exergonic redox reactions occur as part of the electron transport chain (ETC), which is located in the inner mitochondrial membrane. These redox reactions involve the transfer of electrons from electron donors (such as NADH and FADH2) to electron acceptors (such as molecular oxygen, O2).
