Name the type of carbohydrate that can be digested by ruminants but not by humans. Give the reason also.
Cellulose is the type of carbohydrate that can be digested by ruminants but not by humans because the enzymes that digest cellulose are not present in humans. Also, ruminants have a rumen, a large sac-like structure between the esophagus and small intestine.
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 the rumen, and the animals are called 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. Later, the partially digested food is regurgitated to chew their cud. Cellulose is not digestible by the human digestive system. However, this fibrous component helps in the smooth functioning of the intestinal tract.
