Question

Quizplus · Accepted Answer

The last step in glycolysis involves the production of ATP from phosphoenolpyruvic acid (PEP) to pyruvate, catalyzed by the enzyme pyruvate kinase. This step occurs after the oxidation of glyceraldehyde-3-phosphate and is the final step in the conversion of glucose to pyruvate, yielding ATP.
