Question
Chapter 11, Problem 4SYK
Summary Introduction
To explain: The way in which the phosphorylation cascade produces an amplified response to a signal molecule.
Introduction: The phosphorylation is a process of chemical addition of phosphoryl group to the protein. It is carried out by the enzymes. Phosphorylation reaction occurs as a series of reactions or cascade and results in the enhancement of signal.
