**Insulin regulates the reaction in glycolysis where PEP is converted into pyruvate. This reaction is regulated by the enzyme pyruvate kinase. Insulin '''activates''' this enzyme by ''dephosphorylation'' via protein phosphatase 1 (PP1). This increases metabolism. | **Insulin regulates the reaction in glycolysis where PEP is converted into pyruvate. This reaction is regulated by the enzyme pyruvate kinase.
