Signal transduction is the process of transferring a signal throughout an organism, especially across or through a cell. Figure 1 below shows cellular response as the final step of the cell signaling process. As such, the binding of a single epinephrine molecule to a liver or muscle cell-surface receptor can cause the release of hundreds of millions of glucose molecules from glycogen as a result of signal amplification.
