Plаce the stаges оf the cоmplete оxidаtion of glucose in the correct chronological order by filling in the blanks below. The process begins in the cytosol with [BLANK-1], where glucose is broken down into two molecules of pyruvate. Pyruvate then enters the mitochondria and is converted into [BLANK-2] during the "intermediate" or transition step. This molecule then enters the [BLANK-3] (also known as the Citric Acid Cycle), where carbon dioxide is released, and electron carriers (NADH and FADH2) are loaded with electrons. Finally, these carriers deliver their electrons to the [BLANK-4], where the majority of ATP is synthesized through oxidative phosphorylation.
