Cellular Respiration
The Mitochondrial Pathway
Glycolysis
 A series of anaerobic reactions that
take place in the cytoplasm
 The breakdown of glucose into 2
three carbon molecules called
pyruvate (pyruvic acid)
 Generates 2 of the 36 ATP
molecules
Glycolysis diagram
Aerobic Respiration
 Requires Oxygen
 Is more efficient than anaerobic
respiration
Krebs Cycle
 Also known as the Citric Acid Cycle
 Takes place within the matrix (Jell-O)
of the Mitochondria
 Utilizes the pyruvate from glycolysis
to make a coenzyme
 The coenzymes of the Krebs cycle
produces 2 molecules of ATP and 4
molecules of Carbon dioxide
Krebs Cycle
Electron Transport Chain
 Takes place within the membrane of
the Mitochondria
 Is series of reactions where
electron carriers (NADH and FADH2)
transfer energy to generate 32 ATP
ANAEROBIC RESPIRATION
Does not require oxygen
Fermentation
 A series of anaerobic reactions that utilize the
pyruvate from glycolysis and to form lactic acid
or carbon dioxide and ethyl alcohol
 There are 2 types
 Lactic Acid Fermentation: takes place in the
muscle cells resulting in the release of lactic
acid
 Alcohol Fermentation: takes place in yeast
and bacteria resulting in the release of
carbon dioxide and ethyl alcohol
Cellular Respiration Equation
C6H12O6 + 6O2  6CO2 + 6H2O + 36 ATP
