Cellulose is a carbohydrate which is present in the plant cells. The cellulose is a polymer with glucose as the monomer units. The monomer units of cellulose is attached by the beta linkages.

Some animals, such as cows and termites have these enzymes but not the humans.
Hence, the answer is 'people cannot digest cellulose'.
