No. Animals do not produce enzymes that hydrolyze cellulose. (From Master Bio - Chapter 41).
Cellulose bonds are not hydrolyzed by human enzymes.
Ruminant animals have 4 stomachs but the microbed don't produce cellulose, they break it down.
Some protistas include naked and shelled amoebas and algae or diatoms.
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.
Cows do not digest cellulose cell walls because they, as an animal, are incapable of producing a special enzyme, called cellulase, to do the job. The cellulose-digesting bacteria in their rumen, however, are capable of producing such an enzyme and are thus responsible for digesting cellulose and helping the cow obtain essential nutrients from coarse plant material where she cannot.
No. Animal cells have no cell walls. Actually, urochordates (tunicates) produce cellulose. whats funny is they didnt ask if they had cell walls. Smooth....
Photosynthesis
There are several things that can break down cellulose. Most are anaerobic bacteria like cellulomonas and are found in the stomachs of cows and sheep.
Ribosomes produce enzymes .
Enzymes
IT Produces Both xx
They produce digestive juices, a combination of chemicals and enzymes including; HCL, intrinsic factor, and pepsinogen.
Cellulose has beta C1-C4 bonds between the glucose molecules - i.e. carbon 1 of 1 molecule bonds to carbon 4 of another. Animals don't produce the enzymes to break down cellulose but cows, rabbits etc. can only break it down due to symbiotic bacteria in their intestinal tract which possess the required enzymes to breakdown cellulose. In plants, cellulose is a strong supporting material because hydroxyl groups project out from each chain, forming hydrogen bonds with neighbouring chains - creating a rigid cross-linking between the chains. It is fully permeable to water and solutes which means it can allow them to move in and out of cells.
