The conversion of the message into a form that can elicit a particular cellular response

The early work of Earl W. Sutherland suggested that the process going on at the receiving end of the cellular conversation can be dissected into three stages: reception, transduction, and response. The detection of signal molecules coming in from another cell is known as Reception. The conversion of the message into a form that can elicit a particular cellular response is known as Transduction. In the last stage, a Response is triggered by the transduced signal. This response may include any cellular activity.
