Question 1 of 120 answered
Which enzyme is primarily inhibited by thioamide antithyroid drugs to block thyroid hormone synthesis?
Incorrect
Correct answer: Thyroid peroxidase
Thioamides bind to thyroid peroxidase and prevent oxidation of iodide, iodination of tyrosyl residues, and coupling of iodotyrosines, thereby inhibiting synthesis of $T_4$ and $T_3$ (onset delayed until stores are depleted, ~3–4 weeks).
