Question

Choose the correct answer from the alternatives given.
Which of the following hormones is incorrectly paired with its action?

• A. Oxytocinstimulates uterine contraction in childbirth
• B. Thyroxinestimulates metabolic processes
• C. Insulinstimulates glycogen breakdown in liver
• D. ACTHstimulates release of glucocorticoids by adrenal cortex

Answer 1

The correct option is C Insulinstimulates glycogen breakdown in liver

(A) Oxytocin initiates vigorous uterine contractions in females at the time of the childbirth, milk secretion by mammary glands, contraction of smooth muscles.

(B) Thyroxine is primarily responsible for regulation of metabolism.

(C) Insulin stimulates conversion of glucose to glycogen (glycogenesis).

(D) ACTH stimulates the synthesis and secretion of steroid hormones called glucocorticoids.

So the correct answer is insulin stimulates glycogen breakdown in liver.
