Eventually, the end product of glycogenolysis in skeletal muscle will be ATP in order to produce energy for muscle activity. Unlike the glycogenolysis in the liver, the produced glucose from glycogenolysis in the skeletal muscle is not released in the blood stream, because it will directly go to the glycolysis pathway to be consumed to generate pyruvate. Pyruvate will be converted to acetyl-coA to be used in citric acid cycle for production of ATP.
The end product of glycogenolysis in the liver is glucose. Glycogen stored in the liver is broken down into glucose, which can then be released into the bloodstream to provide energy to cells throughout the body.

Insertion point, which most probably is a tendon.
The "movable" end of a muscle is called the insertion. The "immobile" end is called the origin. Shortening, or contraction, of a muscle causes the origin and insertion to become closer to one another.
The substance that becomes an end product of respiration in muscle cells is latic acid. This will happen commonly at the end of a strenuous exercise.
Both skeletal and cardiac muscles are striated muscles.
The end of the muscle that is attached to the stationary bone is the point of origin. The muscle end that is attached to the moving bone is the point of insertion, and the action is what the muscle actually does.
Anaerobic fermentation enables a cell to produce ATP in the absence of oxygen but the ATP yield is very limited and the process produces a toxic end product, lactic acid, which is a major factor in muscle fatigue.
The organization of contractile proteins into a regular end-to-end repeating pattern of sacromeres along the length of each cell accounts for the striated, or striped, appearance of skeletal muscle in longitudinal section.
