Carolina Duffy · Answer 1

The correct answer is option C. they amplify the original signal manyfold.

Explanation:

A phosphorylation cascade is a chain or sequence of the reactions that are categorized by the events where one enzyme phosphorylation another up-to phosphorylation of thousands of proteins.

The phosphorylation cascade can be experienced in involving the protein kinases as they the signal transduction of different cellular hormone messages due to their ability to amplify the original signal multiple time and make it more effective.

Thus, the correct answer is option C.
