Document Summary
Glycogen granules in human muscle: black dots are muscle glycogen stored within the muscle, they are interfibral store of muscle glycogen, located between the myofibrals, under the sarcolemma, there is a sub-sarcolemma deposit of muscle glycogen. There are also stored within the myofibrils as well, called intrafibral stores. Glycogenolysis & glycolysis: sources of glucose: stored muscle glycogen and glucose coming in through glycolysis. Glycogen & glucose use during exercise: shows relationship between muscle glycogen and glucose used during exercise. There will always be residual amount of glycogen in the muscle. If you have a rise in blood glucose levels rise in insulin and fall in glucagon. Sympathoadrenal activity: epinephrine and norepinephrine, this will allow breakdown of liver glycogen so there is glucose in the blood. Cho availability will have effect on liver glucose output. Cho ingestion and muscle glycogen during exercise: cycling from long period of time, looked at glycogen concentration in muscle and looked at control and.
