Chapter 9.1, Problem 3CC
Summary Introduction
To explain: The reason for necessity of signal transduction pathway for most signaling molecules to have an effect.
Introduction: The signal transduction pathway is consist of series of molecular events through which a signal is transmitted in a cell resulting in a cellular response. The molecule which detects the signal is known as receptor.
