Liver and skeletal muscle have different isozymic forms of glycogen phosphorylase that vary in a number of ways as discussed in the text. One notable difference is that the $V_{max}$ of muscle phosphorylase is considerably larger than the $V_{max}$ of liver phosphorylase. Why does this difference make good physiological sense? Muscle cells derive most of their energy from glycogen mobilization. The concentration of glycogen is higher in the muscle than in the liver. The ATP needs of the liver are less variable than those of the muscle. The muscle maintains glucose homeostasis of the organism as a whole.
