Many animals, including humans, cannot digest
(a) amino acid
(b) bile juice
(c) cellulose
(d) proteins

Correct Answer: (c) cellulose

Explanation:

Cellulose is not digestible by the human digestive system. However, this fibrous component helps in the smooth functioning of the intestinal tract.

In animals like Termites, the cellulose is digested by microbes present in the gut or stomach.

In herbivores, there is a different compartment in the stomach for the digestion of cellulose which is known as rumen and the animals are called as ruminants.

The ingested food containing cellulose is stored in the rumen temporarily. The bacteria and enzymes present in the rumen conduct anaerobic bacterial digestion of cellulose.
