This chapter explores the intricate regulation of glycolysis, emphasizing critical enzymes such as hexokinase, phosphofructokinase-1, and pyruvate kinase. It delves into mechanisms of lactate formation, the Cori cycle, and alcohol fermentation, highlighting the free energy changes involved. Additionally, we discuss the effects of ATP, ADP, AMP, and the regulation of phosphofructokinase by fructose-2,6-bisphosphate. The chapter concludes with insights into insulin-induced glucose transporter exocytosis and the impact of glucagon on liver PFK-1, alongside how various sugars enter glycolysis.
