Which of the following statements are correct?
(A) Glucocorticoids control the carbohydrate metabolism
(B) Testosterone is a major female sex hormone
(C) Insulin is released in response to increase in blood sugar
(D) Hypothyroidism is caused by low level of thyroxine
(E) Mineralocorticoid is a major male sex hormone
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A), (C) and (D) only
(A) Glucocorticoids control the carbohydrate metabolism — Correct. Glucocorticoids from the adrenal cortex control carbohydrate metabolism.
(B) Testosterone is a major female sex hormone — Incorrect. Testosterone is the major male sex hormone; estradiol is the main female sex hormone.
(C) Insulin is released in response to increase in blood sugar — Correct. Insulin lowers the blood glucose level when it rises.
(D) Hypothyroidism is caused by low level of thyroxine — Correct. Too little thyroxine from the thyroid gland causes hypothyroidism.
(E) Mineralocorticoid is a major male sex hormone — Incorrect. Mineralocorticoids control the excretion of water and salt by the kidney.
NCERT (2026-27 edition):
Hormones – “… Hormones have several functions in the body. They help to maintain the balance of biological activities in the body. The role of insulin in keeping the blood glucose level within the narrow limit is an example of this function. Insulin is released in response to the rapid rise in blood glucose level. On the other hand hormone glucagon tends to increase the glucose level in the blood. The two hormones together regulate the glucose level in the blood. Epinephrine and norepinephrine mediate responses to external stimuli. Growth hormones and sex hormones play role in growth and development. Thyroxine produced in the thyroid gland is an iodinated derivative of amino acid tyrosine. Abnormally low level of thyroxine leads to hypothyroidism which is characterised by lethargyness and obesity. …
Steroid hormones are produced by adrenal cortex and gonads (testes in males and ovaries in females). Hormones released by the adrenal cortex play very important role in the functions of the body. For example, glucocorticoids control the carbohydrate metabolism, modulate inflammatory reactions, and are involved in reactions to stress. The mineralocorticoids control the level of excretion of water and salt by the kidney. … Testosterone is the major sex hormone produced in males. It is responsible for development of secondary male characteristics (deep voice, facial hair, general physical constitution) and estradiol is the main female sex hormone.”
