Which of these statements describes thyroxin
A)It is formed by coupling one MIT and one DIT within the colloid.
B)It is produced by the C cells of the thyroid gland.
C)It exerts a calorigenic effect.
D)It inhibits thyroid-stimulating immunoglobulin in a negative-feedback fashion.

Question

Quizplus · Accepted Answer

Thyroxin exerts a calorigenic effect, meaning that it increases metabolic activity and heat production in the body.

Other statements:
A) Thyroxin is formed by coupling two molecules, one of diiodotyrosine (DIT) and one of monoiodotyrosine (MIT), within the colloid.
B) Calcitonin is produced by the C cells of the thyroid gland, not thyroxin.
D) Thyroxin does not inhibit thyroid-stimulating immunoglobulin. It is regulated by negative-feedback mechanisms involving thyroid-stimulating hormone (TSH) from the pituitary gland.
