Question

why is cellulose is not digested in human alimentary canal​

Answer 1

Answer:

Humans are unable to digest cellulose because the appropriate enzymes to break down the beta acetyl linkages are lacking.

Explanation:

Cellulose is found in abundance in nature in virtually all plant tissues and is therefore a common component of our diet.

Humans cannot digest cellulose as theirdigestive system does not have cellulase, the enzyme which digests the cellulose.

Dieticians and nutritionists identify cellulose to be the useful part of food that keeps the move through the digestive tract efficient. Undigested cellulose is the fibre which aids in the smooth working of the intestinal tract. (hope you like it add me in brain list)

Answer 2

Answer:

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. Animals, such as cows, sheep and horses, can digest cellulose, which is why they can get the energy and nutrients they need from grass.
