Discuss the differences in the function and the mechanism of glycogen mobilised in the liver, compared with glycogen mobilised in skeletal muscle.
In the liver, glycogen stores are converted to glucose 6-phosphate, which is then converted to glucose for release into the blood and transport to tissue.
In skeletal muscle, the glucose 6-phosphate is metabolised directly to obtain energy (ATP) during activity, as muscles only mobilise glycogen that they need for themselves.
Liver breaks glycogen down for the whole family, right down to glucose.
Skeletal muscle only breaks down glycogen for itself, and doesn't need to break it down all the way.
