Hormone-Receptor Interaction

  Hormones are carried by the circulation to all tissues, but they affect only certain tissues. Tissues responsive to specific hormones have specific protein receptors capable of binding those hormones. These protein receptors should not be viewed as static fixtures asso ciated with cells, but like any cellular structures, they are subject to change. The […]

Metabolism and Excretion of Hormones

    The concentration of a hormone in the plasma is also influenced by the rate at which it is metabolized (inactivated) and/or excreted. Inactivation can take place at or near the receptor, or in the liver, the major site for hormone metabolism. In addition, the kidneys can metabolize a variety of hormones, or excrete […]
