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.
No.
Humans are unable to get metabolic energy from cellulose because they lack the enzymes necessary to chemically break it down. Since the human body can't properly digest cellulose, it's passed in the feces.
Ants cannot digest cellulose. Termites can, but only because of symbiotic microorganisms in their digestive system. Termites are sometimes called white ants but they belong to a completely different insect order.
No. Animal cells have no cell walls. Actually, urochordates (tunicates) produce cellulose. whats funny is they didnt ask if they had cell walls. Smooth....
The breakdown of proteins is a problem for animals for quite a few reasons. Proteins are complex and some animals don't have the ability to break them down.
No. Animals do not produce enzymes that hydrolyze cellulose. (From Master Bio - Chapter 41).
No
No.
No !
yes
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.
Ruminant animals have 4 stomachs but the microbed don't produce cellulose, they break it down.
Yes, animals like cows and termites can effectively digest cellulose in their diet with the help of specialized microorganisms in their digestive systems.
HUmans haven't got the digestion system needed to break down cellulose into nutrients. Animals, with longer intestines can.
2 polysaccharides found in plants are starch and cellulose. :)
Cellulase is mainly produced by microorganisms like fungi and bacteria, not by plants or animals. Although animals, including termites and some ruminants, can host microorganisms that produce cellulase to help them digest cellulose-rich plant material.
