Final answer:
Oxidative phosphorylation is the final stage of cellular respiration, where ATP is produced through the electron transport chain and chemiosmosis. NADH and FADH2 are the primary reactants, and the products are water and ATP.
Step-by-step explanation:
Oxidative phosphorylation is the final stage of cellular respiration, where ATP is produced through the electron transport chain and chemiosmosis.
The primary reactants of oxidative phosphorylation are NADH and FADH2, which donate high-energy electrons to the electron transport chain. These electrons pass through a series of redox reactions in four large protein complexes embedded in the inner mitochondrial membrane, ultimately reducing oxygen to form water as the primary product.
During this process, hydrogen ions are also transported across the membrane, creating a gradient that drives ATP synthesis through chemiosmosis.
