glycogen decreases.

B.) The level of the hormone insulin increases, while the amount of glycogen increases.

C.) The level of the hormone insulin remains very low, while the level of glucagon

decreases.

D.) The level of the hormone insulin decreases, while the level of glycogen increases.

E.) Insulin and glucagon both decrease.

5.) When a person with Type 1 diabetes eats a meal and blood glucose levels increase

A.)The level of the hormone insulin increases, while the level of glycogen decreases.

B.) The level of the hormone insulin remains very low, and the level of glycogen remains

low.

C.) The level of the hormone insulin decreases, while the level of glucagon decreases.

D.) The level of the hormone insulin decreases, while the level of glycogen increases.

E.) Insulin and glucagon both increase.

6.) When a person with Type II diabetes eats a meal and blood glucose levels increase,

A.) The level of the hormone insulin increases, and the level of glycogen increases.

B.) The level of the hormone insulin remains very low, while the level of glucagon

increases.

C.) Insulin and glucagon both decrease.

D.) The level of the hormone insulin increases, while the level of glycogen remains about

the same.

E.) Insulin and glucagon both increase.

Explanation / Answer

The answer to question 4

After the consumption of food, in normal man, the glucose level increases. This triggers the beta cells of the pancreas to secrete insulin. As a result, the insulin blocks the conversion of glycogen to glucose in the liver. However, insulin increases the secretion of glycogen by reducing the phosphorylation of glycogen synthase.

Hence, in a normal man, after he has eaten a meal, Option B - the level of the hormone insulin increases, while the amount of glycogen increases.

The answer to the question 5

Type 1 diabetes is a condition in which the beta cells fail to secrete insulin. Even if it secretes, the insulin levels will be very low.

Hence, when a person with Type 1 diabetes eats a meal and blood glucose levels increase, Option B - The level of the hormone insulin remains very low, and the level of glycogen remains low.

The answer to the question 6

Type 2 diabetes is characterized by the non-usage of insulin in our body. As a result, the person becomes insulin resistant. This eventually leads to increased accumulation of glucose and decreases the production of glycogen.

Hence, when a person with Type II diabetes eats a meal and blood glucose levels increase, option D - the level of the hormone insulin increases, while the level of glycogen remains about the same.
