The hormone-receptor complex switches on or switches off specific biological processes in cells, tissues, and organs. When a hormone binds to a receptor, the receptor carries out the hormone's instructions, either by altering the cell's existing proteins or turning on genes that will build a new protein.
Much like a lock and key, many hormones act by binding to receptors that are produced within cells. body growth and energy production (growth hormone and thyroid hormone).differentiation, growth, and function of reproductive organs (testosterone and estradiol) and.Hormones control or regulate many biological processes and are often produced in exceptionally low amounts within the body. Over 50 hormones have been identified in humans and other verterbrates. Although hormones reach all parts of the body, only target cells with compatible receptors are equipped to respond. Hormones act as chemical messengers that are released into the blood stream to act on an organ in another part of the body. Where are endocrine glands located in the human body?.
