Cell signalling is a process by which cells communicate with each other and transfer messages.
<h3>What is a receptor?</h3>
A molecule inside or on the surface of a cell binds to a specific substance and causes a specific effect in the cell.
Cell signalling is a process by which cells communicate with each other and transfer messages. When a signal molecule binds to a receptor protein, changes occur in the receptor proteins. Two changes are listed below:
1. The receptor protein undergoes conformational changes and acts as an enzyme.
2. The receptor protein that makes a second messenger molecule that leads the reaction further to other cells or molecules.
