The breakdown of glycogen (an energey- storage compound) is an example of a(n) _____ reacction?
Glycogenolysis reaction:
First explanation;
Glycogenolysis is the breakdown of glycogen (n) to glucose-1-phosphate and glycogen (n-1). Glycogen branches are catabolized by the sequential removal of glucose monomers via phosphorolysis, by the enzyme glycogen phosphorylase.
Or second explanation;
Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen. The reaction takes place in the hepatocytes and the myocytes. The process is under the regulation of two key enzymes: phosphorylase kinase and glycogen phosphorylase.
The breakdown of glycogen (an energey- storage compound) is an example of a(n) _____ reacction?
Which of the following about glycogen storage is NOT correct? Glycogen storage occurs in the form of dense granules in the cytoplasm of cells. Glycogen is stored mainly in the skeletal muscles and liver. Glycogen nearly fills the nucleus of cells that specialize in glycogen storage. Glycogen is linked with alpha 1,4 glycosidic linkages For this question use this figure. The numbers correspond to the different protein forms of phosphorylase in the muscle. 1 TAGE Phosphate group 2ATP ZAP Which...
7. Which statement is TRUE of glycogen synthesis and breakdown?---->the answer is A but I need it explained to me. a. Phosphorylation activates the enzyme responsible for breakdown, and inactivates the synthetic enzyme. b. Synthesis is catalyzed by the same enzyme that catalyzes breakdown. c. The glycogen molecule "grows" at its reducing end. d. The immediate product of glycogen breakdown is free glucose. e. Under normal circumstances, glycogen synthesis and glycogen breakdown occur simultaneously and at high rates.
When an individual is in a “fight-or-flight” situation, the release of epinephrine promotes glycogen breakdown in the liver, heart, and skeletal muscle. The end product of glycogen breakdown in the liver is glucose; the end product in skeletal muscle is pyruvate (because it is immediately used by glycolytic enzymes). What is the advantage of these specific glycogen breakdown routes in the liver (glucose as final product) and skeletal muscle cells (pyruvate as final product) for an individual that must fight...
Describe the method used to maximize muscle glycogen storage (glycogen loading) (5 pts minimum)
the ______ of the peripheral nervous system promotes the breakdown of glycogen into glucose in the liver. a) sympathetic division b) parasympathetic division c) enteric division d) motor division
Determine whether each phrase describes starch, glycogen, or cellulose. Starch Glycogen Cellulose major storage form of glucose in plants made up of two glucose polysaccharides: amylose and amylopectin major storage form of carbohydrates in animals not digestible by humans Answer Bank
An experiment was performed to determine the effects of an inhibitor on the breakdown of glycogen by an enzyme. In an accompanying experiment, the inhibitor was added to the glycogen-enzyme suspension and reacted using the same experimental conditions. The data obtained from these experiments is tabulated below. Draw the Michaelis-Menten and Lineweaver-Burke plots of these data. Determine the form of inhibition observed from these results and explain your rationale for this form. Determine the values for K_m and V_max from...

A patient was seen by a gastrointestinal specialist and diagnosed with a glycogen storage disease. A liver biopsy showed that the patient was producing very little glycogen, the molecules were relatively small, and they only had a(1,4) glycosidic linkages. Blood and liver glucose concentrations were within normal ranges. What enzyme is likely affected in this disease? a. glycogen synthase b. glycogen phosphorylate c. branching enzyme d. debranching enzyme e. hexokinase
Describe how the opposing processes of glycogen breakdown and synthesis are reciprocally regulated by allosteric interactions and the covalent modification of key enzymes.
