Which of the following statements correctly explains why PFK-1 activity will be higher in nondiabetics than type I diabetics? Glucagon normally stimulates glycolysis in liver cells, but the decrease in responsive glucagon receptors in type I diabetics reduces activation of glycolysis. Insulin normally stimulates glycolysis in liver cells, but the decrease in responsive insulin receptors in type I diabetics reduces activation of glycolysis. Glucagon normally stimulates glycolysis in liver cells, but the lack of glucagon signal in type I diabetics reduces activation of glycolysis. Insulin normally stimulates glycolysis in liver cells, but the lack of insulin signal in type I diabetics reduces activation of glycolysis. Submit Request Answer
