How can paper be chemically changed?
Paper can be chemically changed through processes like oxidation, hydrolysis, or reduction. For example, exposure to oxygen in the air can cause paper to yellow over time due to oxidation. Additionally, acids in the environment can hydrolyze cellulose fibers in paper, causing it to weaken and deteriorate.
What is a cellulose sponge made of?
A cellulose sponge is made of, well, cellulose. Cellulose is the main component of plant cell walls, so many plant derived products are cellulose based. Wood is about 50% cellulose, paper and cardboard are almost entirely cellulose, and most plant fibers are mostly cellulose- cotton is about 90% cellulose. the wikipedia article is decent: http://en.wikipedia.org/wiki/Cellulose
Does iodine react with cellulose?
Iodine can react with cellulose through a process called iodination. When cellulose is treated with iodine, the iodine molecules can attach to the hydroxyl groups on the cellulose chains. This reaction can be used in chemistry to modify cellulose and produce different types of cellulose derivatives.
What ion is expected to hydrolyze in a 0.1 M Na2CO3?
Salts of a strong acid and a strong base: examples: NaCl, KBr, Ba(NO3)2. Neither the cation nor anion hydrolyzes and the solution has a pH of 7.
A scientist has analyzed the chemicals that make of sample of an unknown substance Which chemicals would be the best indicator that the unknown substance is a plant?
Cellulose and starch
Do animals produce enzymes that hydrolyze cellulose?
No. Animals do not produce enzymes that hydrolyze cellulose. (From Master Bio - Chapter 41).
Why can your bodies hydrolyze glycogen and not cellulose?
Humans have enzymes called -amylase in saliva and pancreatic juices that hydrolyze the -1,4-glycosidic bonds of starches, but not the -1,4-glycosidic bonds of cellulose. Thus, humans cannot digest cellulose. Animals such as horses, cows, and goats can obtain glucose from cellulose because their digestive systems contain bacteria that provide enzymes such as cellulase to hydrolyze -1,4-glycosidic bonds
Can Maltase hydrolyze cellulose into Maltose?
No. First of all, the name maltase indicates that the enzyme breaks down maltose. Maltose is a disaccharide composed of two glucose monomers. Cellulose is an entirely different polysaccharide, composed of many monomers of beta glucose. Second, very few organisms have the ability to hydrolyze cellulose. In most organisms including humans, cellulose passes through our digestive tract without changing chemically. This is what we call "fiber". Even though we can get no nutrients from it, cellulose is good for the muscles lining the small intestine.
What you expect to get if you hydrolyze a glycogen molecule?
glucose molecules because glycogen is stored glucose formed from glucose linkages
Why do you have feces?
Feces is a product of the inability to digest certain types of food. Due to the diversity of organic nutrients and structure, it is impossible for an organism to break apart every type of nutrient encountered. One example is cellulose ("fiber"), which is a carbohydrate. Cellulose is found in the cell walls of vegetables. A human digestive system cannot hydrolyze cellulose (certain prokaryotes can), and the cellulose is passed through the alimentary canal as waste/feces.
Why can't you break down cellulose?
Cellulose cannot be easily broken down because it is a complex carbohydrate made up of long chains of glucose molecules linked by beta-1,4-glycosidic bonds. Most organisms lack the enzymes required to hydrolyze these specific bonds, which makes cellulose resistant to digestion. Only certain microorganisms and fungi possess the necessary enzymes, such as cellulases, to break down cellulose effectively. Consequently, cellulose serves as a significant structural component in plant cell walls but is largely indigestible to many animals, including humans.
Does cooking an egg hydrolyze it?
no
Why are starch and glycogen useful as energy storage molecules while cellulose is useful for structure and support 2 Why cant humans break down cellulose?
Starch and glycogen are useful as energy storage molecules because they are made up of glucose units linked in a way that allows for easy breakdown and release of energy when needed. In contrast, cellulose provides structural support due to its rigid, linear chains of glucose linked by β-1,4-glycosidic bonds, which form strong fibers. Humans cannot break down cellulose because we lack the necessary enzyme, cellulase, to hydrolyze these specific bonds, rendering cellulose indigestible.
What would happen to a plant without cellulose in it's cells?
Without cellulose in its cells, a plant would not have the necessary structural support to maintain its shape and grow upright. Cellulose also helps with water and nutrient transport within the plant. Without cellulose, the plant would likely wilt and eventually collapse.
Does Macy's carry hydrolyze?
Yes
1 Why are starch and glycogen useful as energy storage molecules while cellulose is useful for structure and support 2 Why cant humans break down cellulose?
Starch and glycogen are useful as energy storage molecules because they are composed of glucose monomers linked in a way that allows for easy hydrolysis, releasing glucose for energy when needed. In contrast, cellulose has a rigid structure due to its β-glucose linkages, making it ideal for providing structural support in plant cell walls. Humans cannot break down cellulose because we lack the enzyme cellulase, which is necessary to hydrolyze the β-glycosidic bonds between the glucose units in cellulose. As a result, cellulose passes through the digestive system undigested, contributing to dietary fiber instead.
Do buffalo have specialized digestive tract to digest plant cellulose?
Yes, buffalo have a specialized digestive system that includes a four-chambered stomach to efficiently break down and digest plant cellulose. The process of fermentation in the stomach chambers helps them extract nutrients from tough, fibrous material like grasses. This allows buffalo to thrive on a diet of predominantly grasses and other plant material.
