Hydrolysis of glycogen (lysis)occurs in muscle cells for energy production and in liver cells for maintaining blood sugar level.

I have a question on glucose here!

... first convert G1P to G6P and then the almighty glucose 6-phosphatase will cut the phosphate, yielding free glucose. Also, glucagon doesn't trigger glycogenolysis in muscle, only in the liver. therefore the most important is the pathway that yields free glucose, that is exported.

Re: Breakdown of stored glycogen & fat; glycolysis

... done my research but I need clarification/confirmation on how stored glycogen and stored fat enter the cellular respiration pathway. Does both glycogenolysis (breakdown of glycogen into G6P for cellresp.) and lipid catabolism (breakdown of triglycerides for cellresp.) occur inside the cytoplasm ...

epinephrine

You mean glycogenolysis , right? I don't think epinephrine has a direct effect on glycolysis other than to stimulate the production of glucose from glycogen. Beta adrenergic stimulation activates adenyl cyclase which increases ...

Adrenaline and Noradrenaline???

Glycogen is a polysaccharide of glucose (used to store glucose in the liver and muscle cells). Glycogenolysis is the catabolism of glycogen which takes place in the liver and leads to glucose. Glucose then is released in the blood so it incerases blood sugar levels. Gluconeogenesis ...
