Answer:
C
Step-by-step explanation:
Oxidative Phosphorylation: The NADH and FADH2 molecules produced in glycolysis and the citric acid cycle are then used in oxidative phosphorylation. This final pathway takes place in the inner mitochondrial membrane and involves the transfer of electrons from NADH and FADH2 to a series of protein complexes, collectively known as the electron transport chain.
