How do cells use signal molecules
WebJan 15, 2024 · Cell signaling is the process of cellular communication within the body driven by cells releasing and receiving hormones and other signaling molecules. As a process, … WebCell signaling pathways begin when the ligand binds to a receptor, a protein that is embedded in the plasma membrane of the target cell or found in the cell cytoplasm. The receptors are very specific, and each ligand is recognized by a different one. This stage of the pathway is called reception. Molecules that are nonpolar, such as steroids ...
