What is the Difference Between Oxidation and Reduction?

WebOxidation occurs when either oxygen is gained, or there is a loss of electrons. Pyruvate ( C 3 H 3 O 3) is an organic molecule made of a three-carbon backbone, a carboxylate ( R C O O − ), and a ketone group ( R 2 C = O ). Anabolic pathways require energy to buildup or construct molecules, as shown in Figure 1.
