CHAPTER 14.4 Gluconeogenesis –Synthesis of glucose from simpler compounds: gluconeogenesis Today’s Objectives: (To learn and understand the)

Gluconeogenesis: Precursors for Carbohydrates Notice that mammals cannot convert fatty acids to sugars Glycolysis occurs mainly in the muscle and brain Gluconeogenesis occurs mainly in the liver

Synthesis of Oxaloacetate

Oxaloacetate Picks Up Phosphate from GTP The phosphoenolpyruvate carboxykinase reaction occurs either in the cytosol or the mitochondria

Chapter 14: Summary Glycolysis, a process by which cells can extract a limited amount of energy from glucose under anaerobic conditions Gluconeogenesis, a process by which cells can use a variety of metabolites for the synthesis of glucose Pentose phosphate pathway, a process by which cells can generate reducing power (NADPH) that is needed for the biosynthesis of various compounds In this chapter, we learned about:
