• O2 is present
• Occurs in the mitochondrial matrix (very inside

MOVIE A
MOVIE B

• (inside matrix) Pyruvic acid converted to acetyl
  CoA
• CO2 released
• Acetyl CoA enters the Krebs Cycle
• Makes ATP and NADH and FADH2
• CO2 released

Electron Transport Chain and Chemiosmosis

• 2 e- enter electron transport chain
• pump H from the matrix to in between the
  membranes creating a CONC gradient
• CONC gradient drives ATP synthase to make ATP
• H2O released
• 36 molecules of ATP is made overall!
