Receptor Signaling

Receptor signaling is how cells communicate and respond to signals from their environment. Cells have specific proteins called receptors that can detect molecules, such as hormones or nutrients. When a signaling molecule, like a hormone, binds to its receptor, it triggers a series of changes inside the cell, leading to a response. This can involve activating genes, modifying cell behavior, or influencing the cell's function. Essentially, receptor signaling enables cells to react appropriately to various signals, allowing for processes like growth, immune responses, and maintaining balance in the body.
