 What do you notice about this equation?

 Starts in cytoplasm  Finishes in the mitochondria

 Where?  Glucose is split in half, making two pyruvates.  Energy from the broken bond makes  It also makes NAD+ into

 Where?  Acetyl CoA is made using oxygen.  What else is made?

 Acetyl CoA is broken down.  Energy is captured:  NAD+   FAD+ 

and from Glycolysis and Kreb’s Cycle use their energy to do an electron transport chain just like the one in photosynthesis, making and water.

 Glycolysis  Where?  What was made?  What is necessary to go to the next step?  Kreb’s Cycle  Where?  What was made?  Electron Transport Chain  Where?  What was made?  Total ATP from one glucose?

 Fermentation happens after glycolysis.  In animals, pyruvate is turned into lactic acid.  In yeast and bacteria, pyruvate is turned into alcohol.  No more ATP is made, but is turned back into NAD+ so glycolysis can continue.  This is called anaerobic respiration.
