Quizplus · Accepted Answer

The correct sequence for cell signaling is: (3) signal release from source, (2) signal binding to receptor, (4) signal transduction, and (1) alteration of cell function. This reflects the chronological order in which a signal is released, interacts with a cell, and ultimately causes a change in the cell's behavior.
