Name the complex associated with F₀–F₁ in mitochondria. How many ATP molecules are produced when one NADH is oxidized? What is the role of F₀–F₁?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Complex V (ATP synthase) is associated with the F₀–F₁ particle, also called oxysome or elementary particle.
- ATP yield: Oxidation of 1 NADH produces approximately 3 ATP molecules.
- F₀ part: Acts as a proton tunnel, allowing H⁺ ions to flow from the intermembrane space into the mitochondrial matrix.
- F₁ part: Contains ATP synthase enzyme, which catalyzes the phosphorylation of ADP to ATP using the proton-motive force.
