Question

Quizplus · Accepted Answer

The coupling of monoiodotyrosines (MIT) and diiodotyrosines (DIT) takes place while they are still bound to the thyroglobulin molecule within the thyroid follicles. This process results in the formation of the thyroid hormones, triiodothyronine (T3) and thyroxine (T4), which are later released into circulation.
