Cellulose is a type of
(a) fats
(b) carbon dioxide
(c) carbohydrate
(d) all of these

Correct Answer: (c) carbohydrate

Explanation:

A water-soluble and biodegradable organic substance, cellulose is a complex carbohydrate or polysaccharide made of oxygen, carbon, and hydrogen.

It is a key component of the cell walls of plants, including the grains, vegetables, and fruits we consume, and it also helps the plant maintain its rigidity and strength. It is a crucial part of our diet because it is a top source of fibre and is used to manufacture clothing and paper.

Microbes in the gut or stomach of animals like termites break down cellulose. In herbivores, cellulose is digested in a separate area of the stomach called the rumen, and the animals are referred to as ruminants.

Food that has been consumed and contains cellulose is momentarily stored in the rumen. Anaerobic bacterial digestion of cellulose is carried out by the bacteria and enzymes found in the rumen. To chew their cud, the partially digested meal is afterward regurgitated. The digestive system of a human cannot digest cellulose. However, this fibrous substance supports the intestinal tract's efficient operation.
