2023 Manipur Chemical Coordination and IntegrationParathyroid hormone functions Medium Question 17 of 85 in Chemical Coordination and Integration

Given below are two statements: Statement I: Parathyroid hormone acts on bones and stimulates the process of bone resorption. Statement II: Parathyroid hormone along with Thyrocalcitonin plays a significant role in carbohydrate metabolism. In the light of the above statements, choose the correct answer from the options given below:

A Statement I is correct but Statement II is false
B Statement I is incorrect but Statement II is true
C Both Statement I and Statement II are true.
D Both Statement I and Statement II are false.

The answer is A.

Solution

Parathyroid hormone (PTH) does act on bones to stimulate bone resorption, increasing blood calcium levels (Statement I is true). PTH and thyrocalcitonin together play a significant role in calcium metabolism (regulating blood calcium levels), not carbohydrate metabolism — so Statement II is false.
