Khan Academy: The Citric Acid Cycle
Resource provides an overview of the steps of the citric acid cycle, also known as the Krebs cycle or tricarboxylic acid (TCA) cycle. Gives detailed examples of how this amazing cycle works and discusses the products of the cycle.
Khan Academy
Khan Academy: Pyruvate Oxidation
How pyruvate from glycolysis is converted to acetyl CoA so it can enter the citric acid cycle. Pyruvate is modified by removal of a carboxyl group followed by oxidation, and then attached to Coenzyme A.
