What animals can hydrolyze cellulose?

no animal can hydrolyze it microbes in digestive tract-cellulose enzymes cotton is one of purest forms hemicellulose (polysaccharide) beta 1-4 linkage glucose, xylose, arabinose, galactose Pectins citrus fruits, apples, citrus byproducts are readily fermented by bacteria especially in large intestine

Can cellulose be hydrolyzed by most animals?

Starch, whose glucosyl units are linked ?-1,4?, can be digested by most animals. Cellulose, whose glucosyl units are linked ?-1,4?, can be digested only by cattle and other herbivores, because microorganisms present in their digestive tracts have enzymes that hydrolyze ?-glucosides. Termites can also digest cellulose.

Which processes requires hydrolytic enzymes?

Hydrolytic enzymes are grouped under the class Hydrolases. They are a very important part of our body and take part in various biological processes. Various enzymes such as lipases, proteases, carbohydrases, nucleotidases are responsible for breaking down lipids, proteins, carbohydrates, nucleic acids, respectively.

Is a cellulose end product of chemical digestion?

The major site for the absorption of the end products of digestion is the: small intestine. Glucose moves from the GI tract into the circulatory system by the process of: cotransport. Cellulose is a residue of digestion that comes from: carbohydrates.
