Membrane Transport

                    After binding to a receptor on a membrane, the major effect of some hormones is to activate carrier molecules in or near the membrane to increase the movement of substrates or ions from outside to inside the cell. For example, insulin binds to receptors on […]

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 […]
