Explanation:
A phosphorylation cascade can be described or is regarded as a sequence of events, where one enzyme phosphorylates another, causing a chain reaction, leading to the phosphorylation of thousands of other proteins.
Phosphorylation cascades is considered to be important because it plays a vital role in regulating many intra cellular processes such as growth, proliferation and cell division.
In conclusion , it should be understood that, cells make use of phosphoylation cascades for signal transduction, bringing outside stimuli to the interior of the cell, to stimulate a response.
I believe that C is your answer.
Hope this helps~!
