Document Summary

Both animals and plants have cell junctions that, where present, directly connect the cytoplasms of adjacent cells: in these cases, signaling substances dissolved in the cytosol can pass freely between adjacent cells. In animals, growth factors are compounds that stimulate nearby target cells to grow and divide: numerous cells can simultaneously receive and respond to the molecules of growth factor produced by a single cell in their vicinity. This type of local signaling in animals is called. In the third stage of cell signaling, the transduced signal finally triggers a specific cellular response. Reception: a signal molecule binds to a receptor protein, causing it to change shape. Reception of the signal depends on the receiver. The signaling molecule acts as a ligand, the term for a molecule that specifically binds to another molecule, often a larger one: ligand binding generally causes a receptor protein to.
