  • TSH binds to G-Protein in Thyroid Membrane. GDP is exchanged for GTP, increasing cAMP levels, increasing thyroid hormone production.
  • Iodine binds to the tyrosine rings in thyroglobuline, forming T3 and T4 
  • They enter follicular cells through pinocytosis, causing lysosomes to separate the T4 and T3.
