Summary

This episode of the physiology podcast, presented by Yves Muller, focuses on the liver’s carbohydrate metabolism. It begins with an introduction to metabolism, distinguishing anabolism and catabolism. The first part covers Claude Bernard’s historical experiments, including the concept of the internal environment and homeostasis, and the famous ‘washed liver’ experiment that demonstrated the liver’s glycogenic function. The second part describes the structure of glycogen, a branched polymer of glucose, and its role as a storage form. The third part details the processes of glycogenesis and glycogenolysis, including the enzymes and hormonal regulation involved. The fourth part discusses the Cori cycle and the Felig cycle, which recycle lactate and alanine to glucose, and gluconeogenesis, the synthesis of glucose from non-carbohydrate precursors. The episode concludes with a preview of the next topic. The content is well-structured, historically grounded, and provides a comprehensive overview of liver glucose metabolism.
