Cellular signaling pathways involve a series of molecular events initiated by a signal, such as a hormone or growth factor, binding to a receptor on the cell surface. This leads to a cascade of intracellular reactions that ultimately result in specific cellular responses. These pathways are crucial for regulating various cellular processes, including growth, differentiation, and metabolism, and are essential for maintaining homeostasis and responding to environmental changes.
