Chapter 8.6, Problem 3CC
Summary Introduction
To determine:
The reason for considering signal amplification as an advantage for signaling molecules.
Introduction
First messengers are the extracellular signaling molecules that bind to the receptors present on the cell membrane. After binding to these receptors, these molecules bind to the receptors like GPCRs. Second messengers are the molecules that are responsible for relaying the signals inside the cell.
