(a)

Interpretation Introduction

Interpretation:

Whether sucrose is enzyme or not has to be determined.

Concept Introduction:

Enzymes are proteins that serve as biological catalysts for biochemical reactions in organisms. They can enhance rate of reaction. Also, they are highly specific to their reactions. These enzymes can be classified on the basis of their catalyzed reactions such as,

(1) Hydrolase: Enzyme that catalyzes hydrolysis reaction. They can be subdivided into lipase that hydrolyzes ester bond in lipids and proteases that hydrolyze proteins.

(2) Dehydrogenase: Enzyme that catalyzes dehydrogenation reaction.

(3) Oxidases: Enzymes that catalyze oxidation reactions.

Mostly name of enzymes end with suffix $\text{-}ase$.
