A signaling cascade is illustrated by protein kinase protein kinase protein kinase and MAP. What purpose does this cascade serve?

A signaling cascade is illustrated by protein kinase protein kinase protein kinase and MAP. What purpose does this cascade serve? Correct Answer The cascade amplifies the signal.

B. In a signaling cascade, the first activated protein kinase is able to activate multiple copies of the second protein kinase. Then, each copy of the second protein kinase is able to activate multiple copies of the third. Because each protein kinase functions repeatedly until it is dephosphorylated, each step of the cascade magnifies the response.
