This session will outline the cellular mechanisms for harvesting energy from glucose and related sugars. It will briefly outline glycolysis as a mechanism to generate ATP and discuss the fate of the pyruvate produced in glycolysis under anaerobic and aerobic conditions.

Learning Objectives

• To understand how cells harvest chemical energy by oxidizing glucose to pyruvate.
• To know the different ways that pyruvuate is catabolized based upon the presence and absence of oxygen.
• To understand what fermentation is, when it occurs, and why it is important.
• To understand what the Citric acid cycle is, when it occurs, and why it is important.
• To understand what Oxidative Phosphorylation is, when it occurs, and why it is important.
