Question

The thyroid hormones are strored as

• A. Glycoproteins
• B. Thyroglobulin
• C. T3 and T4
• D. Polycyclic hydrocarbons

Answer 1

The correct option is B Thyroglobulin

• Thyroid hormones are two hormones produced and released by the thyroid gland, namely triiodothyronine ($T_3$) and thyroxine ($T_4$).
• The thyroid hormones are stored as Thyroglobulin and are released when the thyroglobulin molecule is taken back up into the follicular cells of the thyroid gland.
  
• Hence the thyroid hormones are stored as Thyroglobulin.
• So, the correct answer is 'Thyroglobulin'.
