What are the products of the Krebs cycle?

The Krebs cycle breaks down pyruvate fully to CO2, producing energy in the form of ATPs and NADH (and FADH2). Glycolysis breaks down glucose to produce NADH, ATP, and pyruvate. The passage of electrons through the electron transport chain results in the formation of H2O and ATP. Photosynthesis results in the formation of O2 and glucose.
