BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Hormones are chemical messengers that affect and manage hundreds of bodily processes. Often, a bodily process involves a chain reaction of several different hormones. A hormone will only act on a part of your body if it “fits”-if the cells in the target tissue have receptors that receive the message of the hormone.

Detailed explanation-2: -For instance, steroid hormones, like the sex hormone groups estrogens and androgens, seek out specific target cells and bind to receptor proteins located inside the nucleus of the cell, as shown below.

Detailed explanation-3: -Hormones can be thought of as chemical messages. From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell. The hormone can also create changes in the cells of surrounding tissues (paracrine effect).

Detailed explanation-4: -Hormones cause cellular changes by binding to receptors on target cells. The number of receptors on a target cell can increase or decrease in response to hormone activity. Hormones can affect cells directly through intracellular hormone receptors or indirectly through plasma membrane hormone receptors.
