The dG' for the fumerase reaction is -3.4kJ/mol, but Δ G' is near 0. What is the ratio of fumarate to malate under cellular conditions at 37.0C?
Is this reaction likely to be a control point in the citric acid cycle?© BrainMass Inc. brainmass.com September 21, 2018, 5:46 am ad1c9bdddf - https://brainmass.com/biology/metabolism/reaction-control-point-and-citric-acid-cycle-37447
Since dG' is near zero, this indicates that the reaction is near equilibrium, since dG' = 0 at equilibrium.
If we assume, that dG' = 0, then we can simplify the question.
At equilibrium, ...
