Answer 2

Answer: Assertion "Goitre is caused due to deficiency of Iodine" is correct but the reasoning  "Iron is essential for the formation of thyroxine hormone" is wrong.

Explanation:

Given assertion is that Goitre is caused due to deficiency of iodine which is actually correct.

• A goitre may develop from an abnormal cell proliferation that causes one or more lumps (nodules) in the thyroid or it may be an overall enlargement of the thyroid. Thyroid hormone levels may rise or fall, or there may be no change in thyroid function in the case of a goitre.
• Iodine deficiency in the diet is the leading cause of goitres in the world. In the United States, where the consumption of iodized salt is widespread, goitres are brought on by illnesses that alter thyroid function or elements that influence thyroid development.

The given reasoning that Iron is essential for the formation of thyroxine hormone is wrong, as Iodine is essential for the production of this hormone.

• Thyroxine is a hormone that the thyroid gland secretes and which primarily controls general metabolic functions like glucose and fat metabolism. The only hormones in the body that need iodine for production are thyroxine and triiodothyronine.
• Thyroxine (T-4) and triiodothyronine are two important hormones that are produced by the thyroid gland, which is located in the lower neck (T-3). These enzymes contribute to the body's total metabolic activity. The only enzymes that need iodine for synthesis are those that produce thyroxine and triiodothyronine.
• It is necessary to speed up metabolism in order to boost protein synthesis, lipid and carbohydrate metabolism, cellular growth, cell division, bone formation, and many other processes.
