- body cells use as much glucose as they can for their energy needs of the moment-excess glucose is linked together and stored as glycogen until the muscles and liver are full to capacity with glycogen-if glucose keeps coming, body tissues shift to burning more glucose for energy instead of fat... body cells use as much glucose as they can for their energy needs of the moment-excess glucose is linked together and stored as glycogen until the muscles and liver are full to capacity with glycogen-if glucose keeps coming, body tissues shift to burning more glucose for energy instead of fat...
You store it: Glycogen Animals (including humans) store some glucose in the cells so that it is available for quick shots of energy. Excess glucose is stored in the liver as the large compound called glycogen. Glycogen is a polysaccharide of glucose, but its structure allows it to pack compactly, so more of it can be stored in cells for later use. If you consume so many extra carbohydrates that your body stores more and more glucose, all your glycogen may be compactly structured, but you no longer will be.
