What is a glucose polymer that also serves as an energy storing polysaccharide?
Glycogen is a glucose polymer that serves as an energy-storing polysaccharide in animals. It is stored in the liver and muscles and can be quickly broken down to release glucose when energy is needed.
Cellulose and starch are both polymers of glucose yet most mammals can use starch but not cellulose as a source of fuel?
mammals have very specific enzymes, one that breaks down starch and another that breaks down glycogen. however, the human digestive system does not have an enzyme to break down the polymer cellulose. cellulose is a straight-chain polysaccharide with glucose-glucose linkages different from those in starch or glycogen. some herbavores such as cattle, rabbits, termites, and giraffes have specially developped stomachs and intestines that hold enzyme-producing bacteria or protozoa to aid in the breakdown of cellulose. it is the different glucose-glucose linkages that make cellulose different from starch. recall that, when glucose forms a ring structure, the functional groups attached to the ring are fixed in a certain orientation above or below the ring. our enzymes are specific to the orientation of the functional groups, and cannot break down the glucose-glucose linkages found in cellulose.
What is the enzyme the breaks down sugar?
Sugars are otherwise known as carbohydrates. There are many different sugars, ranging from the single-monomer monosaccharides, to the polysaccharides like starch and cellulose. Each disaccharide (di-monomer sugars - including maltose and sucrose) and polysaccharide is broken down by one particular enzyme. The general term for carbohydrate-breaking enzymes are carbohydrases.
Does hydrolysis require energy to break down molecules?
Yes, hydrolysis requires energy to break down molecules.
What was the variable in Oswald Avery's experiment?
The variable in Oswald Avery's experiment was the type of enzyme used to break down the polysaccharide capsule in the heat-killed S strain bacteria. By using different enzymes, Avery was able to determine which specific molecule was responsible for transforming the R strain bacteria into the pathogenic S strain.
What do you get when you break-down a polysaccharide?
Monosaccharides.
What kind of polysaccharide cannot be digested by human beings?
Humans cannot break down cellulose because it contains beta glucose and the enzymes that humans have cannot break down beta glucose.
Why cant bacteria break down agarose?
Agarose is a complex polysaccharide that has a structure that bacteria lack the necessary enzymes to break down. Bacteria typically lack the specific enzymes required to degrade the agarose molecule effectively.
What is a nonstrach polysaccharide?
Starch is a glucose polysaccharide that is bonded through alpha-linkage. Our body has an enzyme known as amylase which breaks these bonds and allows it to be digested by the body. Amylase is abundant in the mouth, which is why starch based products break down quickly as you chew them. A few examples of non-starch polysaccharides: Glycogen: A polysaccharide that consists of long chains of glucose, which as you may know, is a primary energy source for the body. It is stored in the liver. Cellulose: This is commonly known as dietary fibre, and is mostly indigestible. Our body does not have the enzymes required to break the beta-links in this glucose polysaccharide, which is why it passes through our system undigested.
What does starch end up as?
Starch is a polysaccharide ie. a very complex carbohydrate. Enzymes break it down into a di-saccharide - maltose. Another enzymes then converts this into the monosaccharide (simple sugar), glucose.
Is cellulose a polysaccharide for energy in plant cells?
Yes, cellulose is a polysaccharide that provides structural support in plant cell walls. It is not used directly for energy storage, but plants break down cellulose into glucose molecules, which can then be used for energy through cellular respiration.
What polysaccharide cannot be digested by humans?
Cellulose is a polysaccharide that cannot be digested by humans due to the lack of necessary enzyme, cellulase, in our digestive system. It passes through the gastrointestinal tract intact and provides bulk to aid in digestion and promote overall gut health.
Where can one learn about Polysaccharide?
The Merriam Dictionary on line is a good place to find out information about Polysaccharide. A person will find the definition of Polysaccharide, the origin and the medical definition. Click on Britannica Encyclopedia half way down the same page and more information will be found about Polsaccharide.
Is Maltese a polysaccharide?
Is Maltase a polysaccharide
What is the hydrolytic product of starch?
glucose maltose and maltotriose
A polymer of carbohydrates is called a?
polysaccharide
A type of polysaccharide that accounts for the strength of plants cells and is not digestible to most animals is?
Cellulose is the type of polysaccharide that accounts for the strength of plant cells and is not digestible to most animals. It provides structural support to plant cell walls and is made up of a long chain of glucose molecules bonded together. Most animals lack the enzymes needed to break down cellulose for digestion.
