There are three main stages in aerobic respiration: glycolysis, the Krebs cycle, and electron transfer phosphorylation (ETP). Each stage makes molecules of ATP in different ways, using different reactants. The following diagram provides a summary of the three stages of aerobic respiration. The diagram shows the reactants used at each stage as well as the products produced at each stage


The following table provides a statement, or description, for each stage. Use the diagram below to help you determine the stage each statement describesThen, in the right-hand column of the table, select which stage each statement describes.
