cells communicate through molecular signals to coordinate functions

Cell signaling, also known as cell communication or signal transduction, is the process by which cells detect and respond to external signals through a series of molecular events. These signals can come from other cells, the environment, or within the cell itself, and they often involve the activation of specific receptors and subsequent pathways that lead to a cellular response, such as growth, division, or apoptosis. This process is crucial for maintaining homeostasis and coordinating complex biological functions.
