Q.

What will be the level of insulin and glucagon in a person fasting for 24hrs?

1. High levels of insulin and glucagon

2. Low levels of insulin and glucagon

3. High levels of glucagon, low levels of insulin

4. Low levels of glucagon, high levels of insulin

Q. Insulin and glucagon are antagonistic in nature.

1. True
2. False

Q.

Assertion [A]: Glucagon lowers the blood sugar level.

Reason [R]: Insulin converts the glycogen stored in the liver to glucose.

1. Both A and R are true and R is the correct explanation of A.
   
   

2. Both A and R are true but R is not the correct explanation of A.
   

3. A is true but R is false.

4. Both A and R are false

Q.

What happens when beta cells of the pancreas release insulin into the blood?

1. The liver breaks down glycogen to glucose.

2. Blood glucose levels rise to a set point and stimulate glucagon release.

3. Body cells take up more glucose.

4. Alpha cells are stimulated to release glucose into the blood.
