Question

Why are cattle able to digest cellulose?

• A. the enzymes in their saliva can break down cellulose
• B. their digestive enzymes degrade cellulose to its monomeric units
• C. their digestive enzymes convert cellulose to glycogen
• D. the microbial flora in their stomachs secrete cellulase

Answer 1

The correct option is D

the microbial flora in their stomachs secrete cellulase

Cattle can digest cellulose because they have cellulose-digesting bacteria called ruminococcus in the rumen. These bacteria produce an enzyme called cellulase that can breakdown cellulose to glucose.
