WebJun 22, 2024 · 1. Reception: A cell detects a signaling molecule from the outside of the cell. A signal is detected when the chemical signal (also known as a ligand) binds to a receptor protein on the surface of the cell or inside the cell. 2. Transduction: When the signaling molecule binds the receptor it changes the receptor protein in some way. WebThe main difference between the different categories of signaling is the distance that the signal travels through the organism to reach the target cell. Paracrine signaling Often, cells that are near one another communicate through the release of chemical messengers (ligands that can diffuse through the space between the cells).
