Assertion(A): Iodine diet is essential for proper body functioning in man.
Reason(R): Iodine helps in the formation of thyroxin which regulates overall metabolism of the body.
A & R both are correct
Both assertion and reason are correct. Iodine assists in formation of thyroxin hormone. Thyroxine essentially contains amino acids and iodine. In absence of iodine, thyroxin production is hampered and that affects the overall metabolism and differentiation of tissues in the body.
