Receptor activity

Receptor activity refers to how certain molecules, like hormones or drugs, interact with specialized proteins called receptors in the body. These receptors are like locks on cell surfaces or inside cells, designed to fit specific molecules (keys). When the right molecule binds to a receptor, it triggers a response inside the cell, such as altering gene activity, releasing chemicals, or changing cell behavior. This process helps regulate many bodily functions, including mood, immune responses, and communication between cells. Receptor activity is essential for maintaining health and is often targeted by medicines to treat various conditions.
