In Theory How Many Protons Could Be Pumped Under Standard $\varepsilon$

question 10

Multiple Choice

In theory how many protons could be pumped under standard state conditions by Complex III per mol of CoQ oxidized,considering the following information? (NOTE: mt = mitochondria)
Coenzyme Q + 2H⁺ + 2 e^- → coenzyme QH₂ $\varepsilon$ ^o ' ≈ 0.040 V
Cytochrome c (Fe³⁺) + e^- → cytochrome c (Fe²⁺) $\varepsilon$ ^o' ≈ 0.270 V
H⁺ (outside mt) → H⁺ (inside mt) ∆G ≈ -20kJ/mol
Faraday constant (F) ≈ 100 kJ/Vmol ∆Gº' = -nF∆E₀'
