molecular signaling

Molecular signaling is the process by which cells communicate and coordinate actions using specific molecules called signals. These signals can be hormones, proteins, or other chemical messengers that travel between or within cells. When a signal reaches a cell, it binds to a specific receptor, triggering a cascade of internal reactions that lead to a response—such as growth, division, or responding to stress. This intricate system allows cells to work together and respond appropriately to changes in their environment, maintaining overall health and proper functioning of the body.
