Explanation: 

Detailed explanation-1: -Hormones are like the body’s communication system. They take messages from one part of the body (the gland) to tell another part of the body (the target cell) to do something important. The endocrine glands influence reproduction, metabolism, growth and many other functions.

Detailed explanation-2: -Hormone receptors are proteins that bind hormones. Once bound, the hormone/receptor complex initiates a cascade of cellular effects resulting in some modification of physiology and/or behavior. Hormones usually require receptor binding to mediate a cellular response.

Detailed explanation-3: -The main two types of transmembrane receptor hormone receptor are the G-protein-coupled receptors and the enzyme-linked receptors.

Detailed explanation-4: -All hormones act only on their target tissues. The ability of a tissue to react to a hormone is due to the presence of a receptor in or at the cell. There are two classes of hormone receptors: those bound to the membrane and those present in the cytosol. Peptide hormones generally act through membrane receptors.
