Question

Quizplus · Accepted Answer

Thyroxin (T4) is a thyroid hormone that exerts a calorigenic effect by increasing metabolic rate and heat production in the body. Option A is incorrect because T4 is formed by coupling two DIT molecules within the colloid. Option B is incorrect because C cells of the thyroid gland produce calcitonin, not thyroxin. Option D is incorrect because thyroxin does not inhibit thyroid-stimulating immunoglobulin.
