A. Apoenzyme

B. Haloenzyme

C. Zymogen

D. Isozyme

E. Lectin - Correct Answer (Lectins are carbohydrate-binding proteins. For example: Hemagglutinin is a microbial lectin protein that binds to sialic acid present on the surface of cells. Sialic acids are family of monosaccharides sugars with a nine-carbon backbone).
