In Cell Signaling, _______

Question

In cell signaling, _______.
A) a message passes through membranes by mechanical pressure
B) the first step is active transport
C) the first step is signal transduction
D) one cell communicates with another by means of a hormone or other regulatory molecule

Accepted Answer

Cell signaling involves communication between cells through the use of hormones or other regulatory molecules. This allows one cell to influence the behavior of another, which is critical for many biological processes. Options A and B are incorrect as they do not accurately describe the process of cell signaling. Option C refers to the second step in cell signaling, which involves the transmission of the signal within the cell once it has been received.
