Following statements are regarding thyroid hormone biosynthesis?
I. The basolateral membranes of thyrocytes facing the capillaries contain a antiporter that transports two Na+ ions and one I– ion into the cell with each cycle, against the electrochemical gradient for I–.
II. Na+/I– symporter (NIS) is capable of producing intracellular I– concentrations that are 20–40 times as great as the concentration in plasma.
III. TSH induces both NIS expression and the retention of NIS in the basolateral membrane, where it can mediate sustained iodide uptake.
