Question

The synthesis of thyroxine is impaired, when the dietary intake of Iodine is below

• A. 10 milligram
• B. 100 microgram
• C. 50 milligram
• D. 50 microgram

Answer 1

Answer: (B)

100 microgram

• Iodine is required for the synthesis of the thyroxine hormone by the thyroid gland.
• The hormone plays a major role in the regulation and control of the various metabolic activities.
• The daily intake of dietary iodine should be about 15-20 mg of iodine.
• When the dietary intake is below 100 micrograms per day, the thyroid gland functioning is impaired.
• The secretion of the hormone thyroxine is decreased and this results in growth and metabolism-related problems.

Thus, the correct answer is option B.
