WebTypes of Signals There are four categories of chemical signaling found in multicellular organisms: paracrine signaling, endocrine signaling, autocrine signaling, and direct signaling across gap junctions (Figure 1). WebList and briefly define the three stages of cell signaling Reception, Transduction, and Response 1. Reception: A signaling molecule binds to a receptor protein, causing it to change shape. 2. Transduction: Cascades of molecular interactions relay signals from receptors to target molecules in the cell. 3.
