- Insulin increases the activities of all of the following enzymes, except:
a) Glucokinase
b) Pyruvate carboxylase
c) Glycogen synthase
d) Acetyl-CoA carboxylase
Explanation:
Insulin increases the activities of all of the following enzymes:
Glucokinase
Phospho-fructokinase
Pyruvate Kinase
Protein phosphatase- I
Important points:
Insulin increases the activity of glycogen synthase by inhibiting cAMP.
Insulin-> Increased activity of Protein phosphatase- I-> De-phosphorylation of Acetyl-CoA carboxylase-> Acetyl-CoA carboxylase activated
Answer: Pyruvate carboxylase
