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. ΔG°ʹ =  ?   kJ · mol−1

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.

ΔG°ʹ =  ?   kJ · mol−1

Follow-up Question

Hello. Thank you for answering my question. I actually tried 92.5 kJ/mol-1 and also 92.484 kJ/mol -1(since it asks to use 3 significant figures), but both answers were wrong.

Is there something I missed? like the unit related?
