Answer :
Answer:
a cellulose is the main substance that makes up the cell walls and fibers of plants
Explanation:
cellulose is ingigestible to most animals because animals do not have the enzymes needed to hydrolyze the glycosidic linkages between the monomer units
The correct answer is - cellulose is a polysaccharide that is indigestible for most animals as they lack bacteria that produce enzyme help in digestion of cellulose.
Cellulose is a structural polysaccharide that is present in most of the plant's structure as present in the cell wall of plant cells and provides support and help in standing in an upright position.
- Humans and most animals lack the enzyme essential to digest cellulose in their bodies.
- Many plants such as hay and grasses have cellulose in the abundance.
- Starch is easily digested as it is also a polysaccharide but is storage-based.
- Cows, ox, horses, and such animals can digest cellulose due to having bacteria in their gut that produce enzymes.
Thus, the correct answer is - cellulose is a polysaccharide that is indigestible for most animals as they lack anaerobic bacteria that produce enzyme help in digestion of cellulose.
