Question

1. What is the effect on glycogenesis and glycogenolysis of

A. Increasing the level of glucagon in the liver.

B. Increasing the amount of insulin in the liver.

C. Increasing the amount of epinephrine.

2. After glycogen reserves are depleted what are the major gluconeogenic precursors of glucose under the conditions of

A. starvation

B. intense exercise

Answer 1

1)

The synthesis of glucose form non-carbohydrate precursors is called glycogenesis and degradation of glycogen into simple glucose molecules is called glycogenolysis. So, both these metabolic actions increase blood glucose concentration. To regulate increased blood glucose concentration Insulin is produced from pancreases and its levels increase in liver.

Thus, the correct option is (B).

2)

After glycogen reserves are depleted what are the major gluconeogenic precursors of glucose under the conditions of starvation. Thus, the correct option is (A).
