Which molecules are not carbohydrates
a. simple sugars
b. disaccharides
c. polysaccharides
d. hydrolytic enzymes

Its d , hydrolytic enzymes

Explanation:

Hydrolytic enzymes are the enzymes that help break down  large molecules in the presence of water

Enzymes are proteins having quarterly or tertiary structure .

While all sugars are considered carbohydrates

Simple sugars are monosaccharides and they combine to form disaccharides and disaccharides combine to form polysaccharide

D. Hydrolytic enzymes

Explanation:

Carbohydrates are known to be the sugars. It is composed mainly of carbon, hydrogen and oxygen. It acts as a chief source of energy. Carbohydrates can be -

However, the hydrolytic enzymes are composed of proteins. They act as a biological catalysts by increasing the rate of the reaction but itself remaining chemically unchanged. Hydrolytic enzyme play an important role in the hydrolysis of a chemical bond of a molecule.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
