Cellulose is indigestible to humans because it acts as a hydrophyllic bulking agent to human feces. It is consist of non-starch polysaccharides. Its a soluble fiber, that's why cellulose is indigestible.
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.
Glucose is a simple sugar that serves as a primary source of energy in living organisms, while cellulose is a complex carbohydrate that serves as a structural component in plant cell walls. Glucose is easily digestible and can be used for energy production, while cellulose is indigestible by humans due to its beta-linkages, but serves important functions in providing plant structure and dietary fiber.
Cellulose fiber is not digested by the human digestive system, but also bear in mind that digestion does not work with 100% efficiency, so even nutrients that we digest are not completely digested. Anything not digested will, in due course, be eliminated in the form of a bowel movement.
Carbohydrates
Cellulose is an unbranched molecule.

Cellulose
The cell wall is made of cellulose. Not only hard, but nearly indigestible.
Primarily cellulose, which unlike animal cells, use cellulose for their cell walls instead of phospholipids. Most animals lack the ability to digest cellulose, except for ruminants like cows, which have an enzyme called cellulase to break this down.
Cellulose from plants because it takes too long to digest
proteins, carbohydrates and fats, (fiber is a carbohydrate that is indigestible, typically cellulose)
In cows and other herbivores, their natural flora of bacteria break down cellulose and make it something they can digest, but in humans our bacteria have no effect on cellulose, so for us it is indigestible.
Dietary fiber is any indigestible sugar polymer (e.g. cellulose, pectin, chitin, inulin, oligosaccharide) or other any similar indigestible plant polymer (e.g. lignin).

Salivary amylase is not able to digest cellulose. Amylase has the ability to digest starch but cellulose is a fibre which in indigestible.
