Question

What is the second messenger in hormones?

Answer 1

Hormones:

1. Hormones are chemical substance produced in the body that controls and regulates the activity of certain cells or organs.
2. The second messenger is the mechanism of the action of hydrophilic hormones with receptors in the target cells.
3. The receptors for hydrophilic hormones are present on the plasma membrane of the target cells.
4. The first messengers interact with receptors on cell membranes which form the Hormone-Receptor Complex.
5. This complex leads to conformational changes in the membrane proteins.
6. It results in the production of second messengers inside the cells.
7. The increase in the cells of second messengers results in a rapid alteration in cellular function.
8. An example is Cyclic-AMP.
