Glycogen content of liver is -

Correct! Wrong!

The glycogen content of liver is 10 g/100 g tissue which is more than in the skeletal muscle (1–2 g/100 g).


But the total quantity of muscle glycogen is more than liver glycogen because of the larger muscle mass.

Most of the liver glycogen is depleted after ------------- hours of fasting,

Correct! Wrong!

After about 18 hours fasting, most of the liver glycogen is depleted, when depot fats are hydrolyzed and energy requirement is met by fatty acid oxidation

Which is FALSE -

Correct! Wrong!

Muscle will not release glucose to the bloodstream, because muscle tissue does not contain the glucose-6-phosphatase.

Energy yield from one glucose residue derived from glycogen is -

Correct! Wrong!

Energy yield from one glucose residue derived from glycogen is 3 ATP molecules, because no ATP is required for initial phosphorylation of glucose (step 1 of glycolysis).


If glycolysis starts from free glucose only 2 ATPs are produced.

Which is FALSE about Glycogenin?

Correct! Wrong!

Glycogenin -primer is essential to accept the glycosyl unit.

Which of the following is FALSE?

Correct! Wrong!

Glycogen synthase -


becomes inactive on phosphorylation

Which of the following is correct?

Correct! Wrong!

The regulation of glycogenolysis in skeletal muscle is by epinephrine.


Glucagon has no effect on muscle glycogenolysis.

All of the following are correct about Von Gierke’s Disease EXCEPT?

Correct! Wrong!

Von Gierke’s Disease -Glucose-6-phosphate is accumulated

When 6 molecules of glucose are entering in this pathway. The ------------ carbon atoms of all 6 glucose molecules are removed as 6 molecules of CO2

Correct! Wrong!

HMP Shunt - When 6 molecules of glucose (6 × 6 = 36 carbons) are entering in this pathway. The first carbon atoms of all 6 glucose molecules are removed as 6 molecules of CO2

Which is the rate limiting step of HMP Shunt?

Correct! Wrong!

First Step of HMP Shunt is the rate-limiting step
