The ΔG°' for the reaction Citrate isocitrate is +6.64 kJmol-1= +1.59 kcalmol-1. The ΔG°' for the reaction Isocitrate α-Ketoglutarate is -267kJmol-1 = -63.9 kcalmol-1 What is the ΔG°' for the conversion of citrate to α-Ketoglutarate? Is that reaction exergonic or endergonic, and why?

Question

Please explain this to me I have no idea how to solve this.

Answer 1

it's exergonic, I think because it's breaking down the steps from citrate to alpha-ketoglutarate (being the "first" step). when bonds break, it's releasing energy.
