Anatomy and Physiology II
Signal transduction is the process by which cells respond to external signals through a series of molecular events that convert these signals into cellular responses. This mechanism is crucial for maintaining homeostasis and regulating various physiological processes, including growth, metabolism, and reproduction. It involves the binding of signaling molecules, like hormones, to receptors on the cell surface, leading to a cascade of intracellular events that ultimately result in a specific response from the cell.
