Answer:
If your body lacks enzymes that break down carbohydrates, it would be unable to get glucose molecules.
If you lacked the enzyme to digest proteins, you may not absorb enough amino acids.

Carbohydrates and proteins are the food materials that are used for the production of energy. Our body cannot absorb carbohydrate so it must be broken down into simpler substance such as glucose molecules by amylase, while proteins are broken down into simpler substances such as amino acids by pepsin enzyme.
