Question

For every two QH₂ (ubiquinol) that enter the Q cycle, one is regenerated and the other passes its two electrons to two cytochrome c₁ centers. The overall equation is:
QH₂+ 2 cyt c₁ (Fe³⁺) + 2 H⁺→ Q + 2 cyt c₁ (Fe²⁺) + 4 H⁺

Calculate the free energy change associated with the Q cycle. Use 3 significant figures.
