  1. Producing amylase
  2. Secreting cellulase enzymes
  3. Absorbing cellulose directly
  4. Converting cellulose into glucose enzymatically
Show answer and explanation

Correct answer: Secreting cellulase enzymes

Humans lack cellulase enzymes. Certain gut microbes produce cellulase, allowing partial digestion of cellulose.
