Which of the following is not true?
A) Every reaction in a metabolic pathway must have a negative DG, or the pathway cannot run.
B) the reaction with the largest negative ÄG is the hexokinase reaction
C) the overall pathway of glycolysis has a negative ÄG
D) all of these are true

Question

Quizplus · Accepted Answer

While most reactions in a metabolic pathway have negative ΔG to favor the forward reaction, there may be some reactions with positive ΔG that are coupled with other reactions with large negative ΔG to drive the reaction forward. Therefore, it is not necessary for every reaction in a metabolic pathway to have a negative ΔG for the pathway to run.
