11
Krebs Cycle
12
B) The Krebs Cycle

• b) - NAD and FAD will be added
• - 1 ATP will be produced

13
C) Electron Transport Chain

1. Final Phase aerobic respiration will produce the
   most ATP
2. Energy lost will be used to move protons
   (hydrogen ions) from Hydrogen into the
   mitochondria inner membrane

14
C) Electron Transport Chain

• 4) Concentration gradient will cause __________
  to begin creating ATP
• 5) Oxygen will accept any remaining electrons
  from the chain forming ____________

15

• 6) Oxygen is used as an electron and proton
  acceptor
• - 4H 4e- O2 ? 2H2O
