Utilization of Skeletal Muscle Glycogen

Phosphofructokinase catalyzes an irreversible step in glycolysis and is subject to allosteric inhibition by 

Coordinated regulation of skeletal muscle metabolism by nucleotides. 

Rate-limiting steps Oxaloacetate - Phosphoenolpyruvate FDP Fructose 6-phosphate Glucose 6-phosphate - Glucose 

The three sources for this glucose synthesis are the following. 

Glycerol The hydrolysis of triacylglycerol to fatty acids by adipocytes releases glycerol, which is released into the plasma and converted to glucose in the liver. It makes only a minor contribution to the total glucose formed, but it helps to conserve protein.
