Answer 1

Answer: (D)

Enzymes are macromolecular biological catalysts. Enzymes accelerate chemical reactions. The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.
Various enzymes which catalyses different convertions are-
Diastace converts Starch $\rightarrow$ maltose
Pepsin converts Proteins $\rightarrow$ peptones
Ptyalin converts Starch $\rightarrow$ sugar
Zymase converts Glucose $\rightarrow$ ethylalcohol
Invertase converts Canesugar $\rightarrow$ Glucose $+$ Fructose
