Pyruvate kinase is responsible for the conversion of:

Question

Quizplus · Accepted Answer

Pyruvate kinase is the enzyme responsible for the conversion of phosphoenolpyruvate (PEP) to pyruvate in the final step of glycolysis. This reaction produces ATP, which is why pyruvate kinase is one of the key regulatory enzymes of glycolysis. Therefore, option C is the correct choice. Option A is incorrect because NADPH is not involved in this reaction, and option B is incorrect because glucose 6-phosphate is not a substrate for pyruvate kinase. Option D is also incorrect because pyruvate is not converted to lactic acid by pyruvate kinase; this reaction is catalyzed by lactate dehydrogenase.
