No. Animals do not produce enzymes that hydrolyze cellulose. (From Master Bio - Chapter 41).
Well, I'm not sure there is a really a "problem" with cellulose, but if you're talking about ingestion and digestion, it really depends on what animal you're talking about. Cellulose is a structural polysaccharide (sugar) that is found in the cell walls of plants. It contains beta 1-4 glycosidic linkages between glucose molecules that cannot be broken in the digestive tract of most animals. However, ruminant animals (cows, goats, sheep) have microorganisms in their gut that can break cellulose down using the enzyme cellulase and the cellulose can then be utilized by the animal. So, for most animals, cellulose cannot be broken down and used.
cellulose
Water is added to the mixture and the mixture is filtered. Sucrose which can dissolve in water passes through the filter but starch and cellulose which do not dissolve, remain as residue. Starch is hydrolyzed to glucose, which will then dissolve in water. Filtration of the above mixture will leave cellulose as the residue.
No.
Polysaccharide cannot be used as an energy source by humans because they are hard to break down. Enzymes find it difficult to break them down into glucose for the body to use as energy.
yes
No !
Cellulose is made in animals, starch is made in plants from polysaccarides
None. Animals that can digest cellulose host special bacteria to digest the cellulose molecules, and humans do not host these.
The cell walls of plants are made of cellulose. Approximately 33 percent of all plant material is cellulose. Humans cannot digest cellulose, but animals such as cows and horses can digest cellulose for food.
Most animals lack enzymes to break beta1-4 linkages
