Question

Give the process/pathway where each of the following enzymes is involved:

a. HMG CoA lyase

b. HMG CoA reductase

c. Acetyl CoA carboxylase

d. Acyl CoA dehydrogenase

Answer 1

a. HMG CoA lyase is an enzyme of Ketone bodies metabolism pathway (Ketogenesis pathway).

It converts HMG-CoA to Acetyl-CoA and Acetoacetate.

b.HMG CoA reductase is an enzyme of Cholesterol Metabolism pathway (Cholesterol synthesis pathway).

It converts HMG-CoA and Mevinolin to Mevalonate.

c. Acetyl CoA carboxylase is an enzyme of Fatty acid synthesis pathway

It converts Acetyl-CoA to Malonyl-CoA.

d. Acyl CoA dehydrogenase is an enzyme of Fatty acids oxidation pathway.

It converts Acyl-CoA to ∆2-trans-Enoyl-CoA.
