Which of the Following is NOT Part of the General

Question

Which of the following is NOT part of the general response of cells during cellular communication?
A)The cell does not return to its normal activities after the signal has exerted its effect.
B)Receptors on the outside of the cell bind to specific signal molecules.
C)A cell-surface receptor molecule becomes activated by binding to a molecular signal.
D)An activated cell-surface receptor transfers the signal to the interior of the cell.
E)The signal is transmitted inside the cell and amplified as a series of proteins are activated in sequence, affecting cellular activities according to the type of signal involved.

Accepted Answer

The general response of cells during cellular communication includes the binding of receptors on the outside of the cell to specific signal molecules, activation of a cell-surface receptor molecule which transfers the signal to the interior of the cell, transmission of the signal inside the cell and amplification as a series of proteins are activated in sequence, affecting cellular activities according to the type of signal involved. However, the cell does eventually return to its normal activities after the signal has exerted its effect. Therefore, option A is NOT part of the general response of cells during cellular communication.
