Question

Follicle cells of the thyroid gland produce thyroglobulin, while follicle cells of the parathyroid produce calcitonin. What do follicle cells of the thyroid gland produce?

1) Thyroglobulin
2) Calcitonin
3) Thyroxine
4) Parathyroid hormone

Answer 1

FINAL ANSWER:
3) Thyroxine

Step-by-step explanation:
Follicle cells in the thyroid gland are responsible for synthesizing and releasing thyroid hormones. The primary product of these follicle cells is thyroglobulin, a precursor protein. Through a series of enzymatic processes, thyroxine (also known as T4) is formed from thyroglobulin. Thyroxine is a crucial thyroid hormone that plays a key role in regulating metabolism and various physiological functions in the body. Calcitonin, on the other hand, is produced by parafollicular cells (C cells) in the thyroid gland, not by follicle cells.

Answer 2

Follicle cells of the thyroid gland primarily produce thyroxine (T4), a hormone instrumental in regulating metabolism. Parafollicular cells within the thyroid produce calcitonin, which regulates calcium levels. The parathyroid glands, distinct from thyroid follicles, produce parathyroid hormone (PTH).

Step-by-step explanation:

Follicle cells of the thyroid gland produce both thyroglobulin and hormones such as thyroxine (T4) and triiodothyronine (T3), which are crucial for regulating metabolism. Specifically, the hormone produced by the follicle cells of the thyroid gland is thyroxine, also known as T4 because it contains four atoms of iodine. Parafollicular cells, which are distinct from follicular cells within the thyroid gland, are responsible for the production of calcitonin, a hormone that helps to regulate calcium levels in the blood. Contrarily, parathyroid hormone (PTH) is produced by the parathyroid glands located on the posterior surface of the thyroid gland.
