Name the substance which is needed continuously by thyroid gland to make thyroxine hormone.
Answers
Your thyroid makes 2 main hormones – triiodothyronine (T3) and thyroxine (T4). Adequate amounts of iodine (a chemical element that's an essential part of our diet) are needed for the thyroid to be able to make these hormones. Another hormone that's produced in your thyroid gland is called calcitonin.
Iodine
Explanation:
Thyroid secretes a hormone called Thyroxine. Thyroid hormone synthesis requires the uptake of iodide by active transport, thyroglobulin biosynthesis, oxidation, and binding of iodide to thyroglobulin, and within the matrix of this protein, oxidative coupling of two iodotyrosines into iodothyronines. Without sufficient iodine, thyroxine secretion will be affected. Deficiency of iodine, causes your thyroid glands to swell leading to a condition called Goiter.
