WebDec 30, 2024 · 6.5: Glycogen Synthesis. Although glucose is the primary fuel for cells, it is not an efficient molecule for long-term storage in complex (i.e. greater than single-celled) organisms. Therefore, in both plants and animals, the glucose molecules are linked together to form polysaccharides known as glucans. Glycogenolysis, the process by which glycogen, the primary carbohydrate stored in the liver and muscle cells of animals, is broken down into glucose to provide immediate energy or to maintain blood glucose levels during times of need. Glycogenolysis is thus the breakdown of glycogen (n) to glucose-1 … See more Glycogenolysis takes place in the cytoplasm of cells in the muscle, liver, and adipose tissue.
