For many mammals, carbohydrates provide a large portion of the daily caloric requirement. To harvest energy from oligosaccharides, they must first be broken down into monosaccharides so they can enter metabolism. Kinases play an important role in almost all metabolic pathways. The figure on the left shows the second phase of glycolysis, which contains two important reactions catalyzed by kinases. The anhydride linkage in 1,3 bisphosphoglycerate is unstable and has a high energy. 1,3-bisphosphogylcerate kinase requires ADP to carry out its reaction yielding 3-phosphoglycerate and ATP. In the final step of glycolysis, pyruvate kinase transfers a phosphoryl group from phosphoenolpyruvate to ADP, generating ATP and pyruvate.
