HUMAN NUTRITION

Detailed explanation-1: -Cellulose is basically a chain of glucose like starch. Unlike starch, cellulose has a bond that cannot be broken down by animals. There are some animals, such as cows, goats and sheeps which graze grass that have symbiotic bacteria in their abdomen which can digest cellulose.

Detailed explanation-2: -Ruminant animals digest cellulose via a symbiotic relationship with ruminal microorganisms. Because feedstuffs only remain in the rumen for a short time, the rate of cellulose digestion must be very rapid. This speed is facilitated by rumination, a process that returns food to the mouth to be rechewed.

Detailed explanation-3: -Ruminants can digest cellulose with the help of bacteria.->The microorganisms like bacteria produce cellulase enzyme which helps in the cellulose digestion.

Detailed explanation-4: -Monogastrics cannot digest the fiber molecule cellulose as efficiently as ruminants, though the ability to digest cellulose varies amongst species.
