Aerobic and Anaerobic
Respiration
By: Mr. Raymond Luong
Aerobic Cellular Respiration
• All plants and animals need oxygen to survive
• Cells use oxygen to obtain energy from food:
aerobic cellular respiration
Aerobic Cellular Respiration
• Glucose reacts with oxygen to form carbon
dioxide, water and energy (ATP)
• C6H12O6 + 6O2  6CO2 + 6H2O + energy (ATP)
• For one molecule of glucose, 36 molecules of
ATP are formed
Aerobic Cellular Respiration
• Cells use ATP to for growth, movement and
building new molecules
• ATP reacts with other molecules, releasing
energy and reforming ADP
Aerobic Respiration
Anaerobic Respiration
Oxygen requirement:
Yes
No
Site of reactions:
Cytoplasm and mitochondria
Cytoplasm
Stages:

Net Production of ATP:
38 ATP per 1 glucose
2 ATP per 1 glucose
Conversion of Pyruvate:
Carbon Dioxide
Lactic Acid or Alcohol
How it recycles NADH:
Electron Transport Chain
Fermentation
Cells that use:
most cells
yeast, prokaryotes, muscle
cells
Production of lactic acid:
Does not produce lactic acid
Produces lactic acid
