Question

Define cell signalling

Answer 1

Cell signaling, also known as cell communication, is the process by which cells communicate with each other to coordinate various functions such as growth, development, immunity, and homeostasis. This communication occurs through the release of signaling molecules such as hormones, neurotransmitters, and growth factors, which bind to specific receptors on target cells and trigger a series of biochemical reactions inside the cell. These signaling pathways can involve both extracellular and intracellular signals and play a critical role in regulating cellular processes and maintaining overall organism function.
