Which of the following mechanisms describes the function of pyruvate dehydrogenase?
A)to convert glucose-1-phosphate to glucose-6-phosphate
B)to inhibit the production of glucose-1-phosphate
C)to catalyze the conversion of glyceraldehyde into pyruvate
D)to stimulate the breakdown of glycogen

Question

Quizplus · Accepted Answer

Pyruvate dehydrogenase is an enzyme complex that catalyzes the conversion of pyruvate to acetyl-CoA, which is then used in the citric acid cycle for energy production. It does not have any role in converting glucose-1-phosphate to glucose-6-phosphate or inhibiting its production, nor does it stimulate the breakdown of glycogen. It specifically catalyzes the conversion of pyruvate.
