WebMay 16, 2024 · How does insulin stimulate the production of glycolysis? High sugar levels stimulate the pancreas to produce insulin, which enhances the entry of glucose into the cell and increases the production of the critical glycolysis enzymes. These actions stimulate glycolysis and lower blood glucose levels. Alternatively] WebVarious signaling pathways governed by insulin converge at the level of transcriptional regulation of the key hepatic gluconeogenic genes PCK1 and G6PC, highlighting this as one of the focal mechanisms through which gluconeogenesis is modulated. gloucestershire skin tear pathway
