Question

why we cannot digest cellulose like the cattle?​

Answer 1

the most main reason for not digesting the cellulose is due to the power reduction of appendix.

the appendix should help to digest cellulose our ancestors but due to the development of fire over a period of evolution we have reduced appendix.

so we cannot digest cellulose as compared to the cattles, due to reduction of appendix

Answer 2

Answer:

Humans, unlike cattle don't have the necessary bacteria in their intestines to make the enzymes called cellulases to break down the 1-4 beta glucose bonds. So we cannot breakdown cellulose into its constituent glucose molecules.
