glycogen degradation

Glycogenin

Protein that is linked to glycogen

Alpha-1,4-glycosidic bonds, alpha-1,6-glycosidic bonds, 8-15

Liver

Where glycogen synthesis and degradation occurs to maintain the blood glucose concentration for the whole body even during the nighttime to fuel the brain

In the muscle itself

Where glycogen breakdown occurs to meet the energy needs of the muscles to create the ATP they require

Glycogen phosphorylase, nonreducing ends

Enzyme that degrades glycogen … , it starts the degradation from the …

Glucose-1-phosphate

Phosphorylase catalyzes phosphorlysis reaction that breaks of a … from the glycogen molecule

Glucose-6-phosphate, phosphoglucomutase

For glucose-1-phosphate to enter glycolysis it first must change to … within the liver only by …

Alpha-1,4-glycosidic bonds

Glycogen phosphorylase cannot cleave near branch points only …

Transferase

For phosphorylase to access a glucose that is inaccessible use to a oligosaccharide … transfers this oligosaccharide to a nearby chain

Debranching enzyme

Enzyme that is used to cleave alpha-1,6-glycosidic bonds to release free glucose

Glucose-6-phosphatase

Enzyme that generates free glucose from glucose-6-phosphate only in the liver

Glycogen phosphorylase

Key regulatory enzyme for glycogen degradation

Epinephrine and glucagon

The 2 hormones that cause breakdown of glycogen

Muscle activity

What cause release of epinephrine

Muscle

Organ that is more responsive to stimulation of glycogen breakdown by epinephrine to fully go through glycolysis and create lactate

Liver

Organ that is more responsive to stimulation of glycogen breakdown by glucagon to create glucose

The depletion of glycogen reserves

The onset of fatigue coincides with
