Ans. They amplify the original signal manyfold.

 Phosphorylation cascade is a series of event in which one enzyme phosphorylate another thereby causing a chain reaction that result into the phosphorylation of thousand proteins. Thus, the enzymes responsible for phosphorylation are known as kinase. Hence, these cascades serve to amplify the original signal and also improving the signal.
