In a cell to cell signaling process, signal transduction can be defined as
A) activation of the receptor
B) initiation of translation and production of new proteins
C) change of an external signal to a sequence of intracellular processes
D) adjustment of number of receptors to the strength of the signal

Question

Quizplus · Accepted Answer

Signal transduction refers to the conversion of an external signal to a series of intracellular processes that ultimately lead to a cellular response. This involves a cascade of molecular events that often involve the activation of receptors and the production of new proteins, but these are not the defining characteristics of signal transduction.
