What is the primary function of the enzyme pyruvate kinase in protein metabolism?
A
To catalyze the conversion of pyruvate to acetyl-CoA
B
To catalyze the transfer of a phosphate group from phosphoenolpyruvate to ADP
✓
C
To catalyze the synthesis of amino acids from keto-acids
D
To catalyze the degradation of proteins into amino acids
Explanation
Pyruvate kinase is an enzyme that catalyzes the final step of glycolysis, transferring a phosphate group from phosphoenolpyruvate to ADP, generating ATP and pyruvate.
