    Cell respiration has three parts: glycolysis, the Krebs cycle, and the electron transport chain. Where in the cell is each found, the molecule(s) that enter each, the molecules at the end of each, and the number of ATPs harvested from each?

    Harvests chemical energy by oxidizing glucose to pyruvate. This occurs in the cytoplasm.
    Glucose + 2NAD + 2ATP ----- 2 Pyruvate + 2NADH + 4ATP

    The bridge between glycolysis and the Kreb's Cycle:
    Pyruvate enters the mitochondria via a transport protein located in the mitochondrial membrane and is converted to acetyl CoA which also releases NADH. ...
