Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell.In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response.Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.his may occur independent of signal transduction stimulation by other molecules, as is the case for the toll-like receptor. It may occur with help from stimulatory molecules located at the cell surface of other cells, as with T-cell receptor signaling.
