Cellular signalling

Cellular signaling is the process by which cells communicate with each other to coordinate their functions. Cells send and receive chemical signals, like hormones, through specific receptor proteins on their surfaces. When a signal binds to a receptor, it triggers a series of events inside the cell, leading to changes in behavior, such as growth, movement, or even cell death. This communication is crucial for maintaining homeostasis, responding to environmental changes, and orchestrating complex processes like immune responses and development. Essentially, cellular signaling ensures that cells work together effectively to support the overall health of an organism.
