The equilibrium for the formation of glyceraldehyde-3-phosphate from dihydroxyacetone phosphate is driven by
A) the negative free energy change for the reaction.
B) having the product of the reaction continuously consumed.
C) coupling to ATP hydrolysis.
D) none of these

Question

Quizplus · Accepted Answer

The equilibrium is driven by the continuous consumption of the product, glyceraldehyde-3-phosphate, in subsequent steps of glycolysis, which pulls the reaction forward.
