RESPIRATION
RESPIRATION
1. The process of breaking down food
molecules to release energy.
2. Converts the energy in glucose to
ATP
3. Occurs in the mitochondria.
MITOCHONDRION
TYPES OF RESPIRATION
Anaerobic – requires no oxygen.
Aerobic – requires oxygen.
ANAEROBIC RESPIRATION
Two types:
Alcoholic Fermentation:
C6H12O6  2C2H5OH + 2CO2 + 2ATP
(glucose) (ethanol) (carbon (Energy)
dioxide)
Lactic Acid Fermentation:
C6H12O6  2C3H6O3 + 2ATP
(glucose)
(lactic acid) (energy)
ALCOHOLIC FERMENTATION
Occurs when bacteria and fungi (yeast) break
down plants (Ex: vegetables and fruit) and
release alcohol or vinegar.
LACTIC ACID FERMENTATION
-Occurs in muscles –
due to a lack of
oxygen.
-Leads to a buildup
of lactic acid in
muscles causing
soreness.
AEROBIC RESPIRATION
C6H12O6 + 6O2  6CO2 + 6H2O + 36ATP
Glucose) (oxygen) (carbon (water) (energy)
dioxide)
Occurs in both plants
and animals
Much more efficient
than anaerobic
respiration.
