Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Humans can not digest cellulose. Which of the following enzymes are needed to digest cellulose?
A
Papain
B
Rumen
C
Amylase
D
Pepsin
Explanation: 

Detailed explanation-1: –>The microorganisms like bacteria produce cellulase enzyme which helps in the cellulose digestion.

Detailed explanation-2: -Cattle can digest cellulose because they have cellulose-digesting bacteria called ruminococcus in the rumen. These bacteria produce an enzyme called cellulase that can breakdown cellulose to glucose.

Detailed explanation-3: -Humans cannot digest cellulose because they lack the enzyme cellulase. The enzyme cellulase along with symbiotic bacteria are what helps animals like ruminants and termites digest cellulose.

Detailed explanation-4: -There are some animals, such as cows, goats and sheeps which graze grass that have symbiotic bacteria in their abdomen which can digest cellulose. Humans do not have these bacteria nor cellulase, the enzyme needed to break the bonds of cellulose whereas the bacteria in a cow’s gut does produce cellulase.

Detailed explanation-5: -Abstract. 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.
