D)thyroxine.

Question

Quizplus · Accepted Answer

Iodine uptake by the thyroid is regulated by thyroid-stimulating hormone (TSH), which is produced by the pituitary gland. TSH binds to receptors on the surface of thyroid cells, stimulating the uptake of iodine and the production of thyroid hormones. Thyroid-regulating hormone (TRH) is produced by the hypothalamus and stimulates the pituitary gland to produce TSH. Goitrogens are substances that interfere with thyroid hormone synthesis and can lead to goiter formation. Thyroxine is a thyroid hormone that regulates metabolism, but it does not directly regulate iodine uptake by the thyroid.
