Pyruvate carboxylase is an example of which class of enzymes?
A) Oxidoreductase
B) Transferase
C) Hydrolase
D) Ligase
E) Lyase

Question

Quizplus · Accepted Answer

Pyruvate carboxylase is an enzyme that catalyzes the ATP-dependent carboxylation of pyruvate to form oxaloacetate. This reaction is a key step in gluconeogenesis. Enzymes that catalyze the joining of two molecules with the concomitant hydrolysis of a diphosphate bond (like ATP to ADP) are classified as ligases, making pyruvate carboxylase an example of a ligase.
