Which is NOT One of the Steps in Cell Signaling

Question

Which is NOT one of the steps in cell signaling?
A)signal transduction
B)obtaining a high density of signaling molecules
C)receptor activation
D)signal termination
E)cellular response

Accepted Answer

Obtaining a high density of signaling molecules is not one of the steps in cell signaling. The steps in cell signaling include signal reception (by a receptor), signal transduction (the conversion of the signal to a cellular response), cellular response (activation of cellular processes or gene expression), and signal termination (ending the signal).
