Question

Cellulose is not digestible by humans due to the absence of which of the following enzymes?

• A. Amylase
• B. Urease
• C. Cellulase
• D. Invertase

Answer 1

Answer:

C. Cellulase

The enzyme cellulase hydrolyses cellulose into glucose and thereby digests it. However, the human stomach does not produce any enzyme capable of digesting cellulose, and hence it cannot be digested.
