Answer 1

Answer: (B)

They are made up of fat and sugar.

Enzymes are the biocatalyst, which remains active during the specific conditions like optimum temperature, specific pH and substrate. This conditions varies for different enzymes. The enzymes gets denature when, the conditions exceedes an optimum value while, it gets deactivated when the conditions, are below an optimum level. Enzymes are proteinaceous in nature, they are not composed of fat and sugar.
So, the correct answer is option B.
