C
Ligands
D
Endocrine Signaling
Explanation: 

Detailed explanation-1: -An enzymatic cascade is a sequence of successive activation reactions involving enzymes, which is characterized by a series of amplifications stemming from an initial stimulus. The product of each preceding reaction catalyzes and is consumed in the next reaction.

Detailed explanation-2: -Enzyme activity. An enzyme’s name is often derived from its substrate or the chemical reaction it catalyzes, with the word ending in-ase. Examples are lactase, alcohol dehydrogenase and DNA polymerase. Different enzymes that catalyze the same chemical reaction are called isozymes.
