Question

pepsinogen is inactive so it can be called as a apoenzyme?​

Answer 1

Answer:

A zymogen or proenzyme is an inactive enzyme precursor. A zymogen requires a biochemical change such as a hydrolysis reaction revealing the active site, or changing the configuration to reveal the active site for it to become an active enzyme. Holoenzymes are the active forms of enzymes. Glycosaminoglycans or mucopolysaccharides are long unbranched polysaccharides consisting of a repeating disaccharide unit. Actinases are not inactive enzymes.
