Krebs cycle: Takes place in the matrix of the mitochondria (the space in the middle). The pyruvate is turned into CO2 (which we exhale) and in the process we strip away High-Energy electrons which go to NAD and FAD to make NADH and FADH2. This step only creates 2 ATP-its main job it to steal all the electrons for the ETC. ................
