Question

Assertion (A): Oversecretion of insulin causes hyperglycemia or diabetes mellitus. 

Reason (R): Oversecretion of insulin can lead to hypoglycemia by casuing excessive uptake of glucose from the blood into the cells, which in turn can lead to increased insulin resistance and ultimately result in hyperglycemia or diabetes mellitus.

1. A is True and R is False.
2. A is False and R is True.
3. Both A and R are True.
4. Both A and R are False.

Options

• (1)

• (2)

• (3)

• (4)

Answer 1

(4)

Explanation:

Excess insulin causes hypoglycemia (low blood sugar), not hyperglycemia or diabetes mellitus. Hyperglycemia and diabetes mellitus are caused by the undersecretion (deficiency) of insulin. Therefore, the Assertion (A) is false.

While oversecretion of insulin causes hypoglycemia due to increased glucose uptake into cells, the sequence stating that this process leads to insulin resistance and ultimately results in diabetes mellitus is scientifically incorrect in this context. Therefore, the Reason (R) is also false. 

Hence, both A and R are false.
