Glycolysis takes place in the cytoplasm

Glycolysis Simplified (greatly ☺☺☺☺)
If oxygen is available (aerobic), then pyruvate enters the Krebs cycle
If oxygen is not available(anaerobic), then pyruvate undergoes fermentation

Mitochondrial Structure
The Krebs cycle takes place across inner membrane space (matrix) of the mitochondrion

The Role of Oxygen (O2)
Oxygen is the terminal (final) electron acceptor
½ O2 + 2H+ + 2e- ���� H2O
∴ Oxygen is needed only in the very LAST step of cellular respiration!

Mitochondrial Structure
Infoldings (cristae) increase the area of membrane surface available for electron transport

Aerobic Respiration
C6H12O6 + 6O2 → 6CO2 + 6H2O + 38 ATP
� The Krebs cycle and electron transporttake place in the mitochondria� The Krebs cycle and electron transport maximize ATP yield
� 38 ATP vs. 2 ATP for fermentation

Anaerobic Respiration(Alcohol Fermentation)
C6H12O6 → 2 CH3CH2OH + 2 CO2 + 2 ATP
glucose ethyl alcohol carbon
dioxide
Alcohol fermentation takes place in yeastand some bacteria, and yields only the2 ATP produced in glycolysis

Anaerobic Respiration(Lactic Acid Fermentation)C6H12O6 → 2 C3H6O3 + 2 ATP
glucose lactic acid
Lactic acid fermentation takes place inanimal cells and some bacteria and fungi;it yields only the 2 ATP produced in glycolysis.
