Question

Which of the following are the reasons why cellulose passes through the

digestive system unchanged?

1. Its large molecular size makes it insoluble in water.

2. It cannot be broken down into simpler monosaccharides in the body.

3. It forms a micelle when it mixes with water in the body.

4. Its helical shape is not recognized by the enzymes for digestion.​

Answer 1

Answer:

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.

The reason is due to the different types of bonding between cellulose and starch. Cellulose has beta-1,4 bonds that are not digested by our enzymes (which can digest alfa-1,4 and alfa-1,6 bonds that are present in starch and glycogen).

So the answer is :

4. It's helical shape is not recognized by the enzymes for digestion.
