WebNov 1, 2002 · This leads to activation of the glycolytic enzyme pyruvate kinase. In addition, insulin treatment has been shown to reduce the activity of the gluconeogenic enzymes phosphoenol pyruvate carboxykinase (PEPCK) and pyruvate carboxylase (PC). Thus, in vitro, treatment of hepatocytes with insulin increases glycolysis and decreases … WebDecreased [glucose], which results in decreased insulin and increased glucagon, causes the deactivation of PFK II and the activation of Fructose 2,6-bisPhosphatase, which converts Fructose 2,6-bisPhosphate to Fructose 6-Phosphate, thereby slowing glycolysis in the liver and conserving glucose when [glucose] is low.

WebAlso, some of the glucose is converted into glycogen, as insulin also activates glycogen synthase (which uses intermediates from glycolysis to make glycogen). Excessive … WebAbstract. One of the important effects of insulin on intracellular metabolism is its ability to stimulate the synthesis of glycogen in muscle and liver. It does this by promoting a net decrease in the extent of phosphorylation of glycogen synthase, the rate-limiting enzyme in the pathway of glycogen synthesis, which increases its activity.
