Cellulose present in plants as a food for cattle but not for human beings because

Options

  1. Ahuman body does not contain cellulase hence cellulase cannot be broken into D-glucose
  2. Bhuman saliva cannot break down plant cellulose in small pieces
  3. Cbile juice present in cattle helps them to digest cellulose
  4. Dhuman beings have a smaller stomach than cattle

Correct answer

A. human body does not contain cellulase hence cellulase cannot be broken into D-glucose

Step-by-step solution

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.
