To produce 4 ATP requires 122 kJ/mol.Which reactions in the glycolytic pathway produce enough energy to be able to overcome this deficit?

Question

Quizplus · Accepted Answer

Hexokinase produces ATP in the first step of glycolysis, but this ATP is used up in the next step by the action of phosphofructokinase-1 (PFK-1). However, PFK-1 produces two ATP molecules later in the pathway, which can help overcome the ATP deficit mentioned in the question. Pyruvate kinase also produces two ATP molecules. Therefore, the combination of hexokinase, PFK-1, and pyruvate kinase can produce enough ATP to overcome the deficit in the question. Choices A, C, and D may produce ATP, but they do not produce enough to overcome the deficit.
