Glycogen is a quizlet
1. The answer is B. Adipose triacylglycerols contain the largest amount of stored energy in humans, followed by protein (even though loss of too much protein will lead to death), muscle glycogen, and liver glycogen. 2. The answer is D. Muscle glycogen is used for energy during exercise.D) glycogen degradation in tree branches. E) removal of unneeded glucose residues at the ends of branches. C) formation of (alpha 1 - 6) linkages during glycogen synthesis. A) catalyzes the conversion of starch into glycogen. B) is the enzyme responsible for forming branches in glycogen.- a glycogen granule begins with glucose linked to a carrier protein glycogenin (37 kd) using a glucose transferase enzyme. this occurs after translation in the ER - the "primed" glycogenin, with 2-8 sugars is substrate for glycogen synthase - glycogen synthase uses UDP-glucose: 1) glucose --> glucose-6-phosphate using hexokinase

Glycogen phosphorylase is the primary enzyme in the breakdown of glycogen and glycogen synthase is the rate-limiting enzyme in glycogen synthesis. The regulation of these two enzymes directly affects the flow of either pathway (i.e., synthesis or breakdown) and both are reciprocally regulated by phosphorylation.

Glycogenolysis is the breakdown of the molecule glycogen into glucose, a simple sugar that the body uses to produce energy. Glycogen is essentially stored energy in the form of a long chain of glucose, and glycogenolysis takes place in muscle and liver cells when more energy needs to be produced.glucagon. a hormone formed in the pancreas that promotes the breakdown of glycogen to glucose in the liver to the bloodstream. glycerol. a liquid obtained from fats and oils (lipids) used as a solvent, an antifreeze, a plasticizer, and a sweetener and in the manufacture of dynamite, cosmetics, liquid soaps, inks, and lubricants.The breakdown of glycogen is an example of a hydrolysis reaction. This is because hydrolysis involves the use of water to break down larger molecules into smaller subunits. In the case of glycogen, hydrolysis breaks the glycosidic bonds between the glucose monomers, releasing them as individual molecules. This process is important in the ...insulin. - primary hormone responsible for regulating conversion of glucose to glycogen. - insulin is a peptide hormone produced from beta cells in the pancreas. - the binding of insulin at cell surface receptors triggers a cascade of protein kinases (kinases phosphorylate) that result in the stimulus of glycogen synthesis.
Glycogen is a polysaccharide because it is composed of many subunits of glucose monomers branched together by alpha glycosidic bonds to form long chains of sugar. Glucose is a monosaccharide (a single sugar molecule with a six-carbon ring) because it cannot be further broken down by hydrolysis into other simple subunits.Q-Chat. ChrisBit.
