The equilibrium for isomerization of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate is favored because
A) the standard free energy is negative
B) glyceraldehyde-3-phosphate is being continuously drained off for the subsequent reaction in the glycolytic pathway
C) the value of the equilibrium constant favors the reaction
D) it is driven by the hydrolysis of ATP

Question

Quizplus · Accepted Answer

The equilibrium is favored because glyceraldehyde-3-phosphate is continuously used in subsequent steps of glycolysis, thus pulling the reaction forward by Le Chatelier's principle.
