The correct answer is: human body does not contain cellulase hence cellulase cannot be broken into D-glucose
The enzyme cellulase present in the stomach of cattle break cellulose into D-glucose and is easily digested. But, it is not present in the human body hence cellulose can not be broken down into D-glucose in human body and can not act as food for human beings.
