GENERAL KNOWLEDGE

Detailed explanation-1: -Humans do not digest cellulose because they do not possess certain enzymes, but it is useful for their digestion because it stimulates the work of intestines. Cellulose enhances the intestinal peristalsis. Peristalsis are series of contractions that allow the progressive movement of food through the digestive tract.

Detailed explanation-2: -Humans cannot digest cellulose, but it is important in the diet as fibre. Fibre assists your digestive system – keeping food moving through the gut and pushing waste out of the body.

Detailed explanation-3: -Cellulose is also an insoluble fiber and does not dissolve in water. When consumed, insoluble fibers can help push food through the digestive system and support regular bowel movements (2).

Detailed explanation-4: -Humans cannot digest cellulose because they lack the enzymes essential for breaking the beta-acetyl linkages. The undigested cellulose acts as fibre that aids in the functioning of the intestinal tract.

Detailed explanation-5: -Humans are unable to digest cellulose because we lack appropriate enzymes (cellulase) to break down this complex substance, cellulose.
