How does insulin affect glycolysis
WebPhosphofructokinase speeds up or slows down glycolysis in response to the energy needs of the cell. Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate. WebInsulin stimulates glycolysis by promoting the uptake of glucose by cells, particularly muscle and adipose tissue, which increases glucose metabolism and reduces blood glucose levels. Insulin achieves this by increasing the expression and activity of the glucose transporter GLUT4, which facilitates glucose uptake into cells.
