Considering that 22.4 kJ/mole is required to transport 1 H+ across the mitochondrial membrane, how much energy is available for proton translocation from the oxidation of FADH2 at Complex II? Answer: 134 kJ/mol Can you please explain why the answer would be 134 kJ/mol?

Aconitase catalyzes the conversion of Citrate to Isocitrate in the TCA cycle. The standard free energy change (AG°) for this reaction is +6.7 kJ/mol. The observed free energy change (AG) for the reaction in pig heart mitochondria is +0.8 kJ/mol. The ratio of [isocitrate]/[citrate] in these mitochondria is: Select an answer and submit.

You are isolating  mitochondria from insect cells and incubating in a test tube with 0.005 M FADH2, 0.05 M ADP and 0.05 M Pi. Assuming, these 3 can enter mitochondria at no cost,no glucose/products of glucose metabolism remain in the isolated mitochondria, and oxygen is present.  Part 1) If all expected reactions go to completion, how much ATP is expected formed?  (0 M)(0.02 M) (0.03 M) (0.05 M) (0.1 M) (0.005 M) (0.01 M) (0.015 M)  Part 2) The ratio of FADH2/FAD at completion of all expected reactions would be? (2) (>>2) (0) (1)  Part 3) After completion of all expected reactions, ratio of H ion concentration inside vs. outside the mitochondrial inner membrane should be?  (<1) (~1) (>1)(0)  Please provide brief explanation

Why are estimates of ATP production from cellular respiration provided in terms of a range (30-32, for example)?
