Question

Why is iodine essential for metamorphosis to take properly in frogs?

Answer 1

Iodine is an essential element of thyroid hormone. The thyroid hormone with its essential iodine constituent is responsible for the control of metabolism and also for metamorphosis. The major function of the thyroid gland is to produce thyroid hormone in an amount sufficient to meet the body's needs. To make thyroid hormone, the thyroid uses iodine. If iodine is not available in the diet, the thyroid may produce an insufficient amount of hormone which will adversely effect the process of metamorphosis.
