A membrane transporter actively accumulates iodide in thyroid cells; this is followed by oxidation to iodine, iodination of tyrosine residues in thyroglobulin, conjugation of two diiodotyrosine groups, and formation of T4 and T3 moieties. These reactions are catalyzed by thyroid peroxidase, which is localized in the apical border of the follicular cell membrane.
Norepinephrine differs from epinephrine by its high affinity for ?-receptors and low affinity for ?2-receptors. In contrast, isoproterenol has high affinity for ?-receptors, but virtually none for ?-receptors (A). norepinephrine ?, ?1 epinephrine ?, ?1, ?2 isoproterenol.

 

By tending towards each other, H2O molecules squeeze apolar particles from their midst. Accordingly, in the organism, apolar particles have an increased probability of staying in nonaqueous, apolar surroundings, such as fatty acid chains of cell membranes or apolar regions of a receptor.
