Because there are bacteria living in our guts which produce the enzyme (called cellulase) necessary to break cellulose into smaller parts. Otherwise it would be indigestable, and come out the way it came in.

How does starch differs from cellulose?

starch is soluble in water, on the other hand cellulose is insoluble. also, the glucose molecules in starch and cellulose are linked differently, making it impossible to be broken down by humans.


What carbohydrate from plant foods cannot be digested by animals and passes through the digestive system?

Cellulose is a complex carbohydrate found in plant cell walls that cannot be digested by any mammal (including humans). This is because mammals lack the enzyme which breaks the β(1,4) linkages found within cellulose.

Which of the molecules above cannot be hydrolyzed by the digestive system of most animals starch glycogen sucrose or cellulose?

Cellulose cannot be hydrolyzed by the digestive system of most animals because they lack the necessary enzyme, cellulase, to break down its β-glucosidic bonds. While starch and glycogen can be digested by animals due to their α-glucosidic bonds, sucrose can be hydrolyzed by the enzyme sucrase. Therefore, cellulose is the molecule that most animals cannot digest.

Is it true or false that cellulose cannot be digested by humans?

True. Cellulose, a type of fiber found in plant cell walls, cannot be digested by humans because we lack the necessary enzymes to break it down.
