Which of the Following Mechanisms Describes the Function of Pyruvate

Question

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

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.
