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.
Ruminants are animals that eat grass. They are specially adapted to digest the cellulose found in grass by having large stomachs filled with fermenting bacteria.
No.
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.
The chamber in the digestive tract of grazing mammals where cellulose is broken down is called the rumen. It is a specialized stomach compartment where bacteria and other microorganisms help digest cellulose by fermentation.
None. Animals that can digest cellulose host special bacteria to digest the cellulose molecules, and humans do not host these.
Yes, animals like cows and termites can effectively digest cellulose in their diet with the help of specialized microorganisms in their digestive systems.
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.
They have appendix as a working organ, its vestigial in humans.
People cannot digest cellulose
Micro-organisms, such as bacteria, are able to digest cellulose. No mammals are able to digest cellulose. This is because cellulose contains a β(1,4) linkage that no mammalian enzyme can break. This is why herbivores must have symbiotic bacteria somewhere in their digestive system that help them break down cellulose.
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.
Cellulose in grass can be broken down by ruminant animals such as cows, sheep, and goats that have specialized stomachs with microbes that produce enzymes to digest cellulose. The microbes ferment the cellulose into simpler compounds that the animal can absorb and use for energy. Humans, however, cannot digest cellulose as efficiently due to the lack of these specialized enzymes.
no
Cellulose.
