Cellular respiration
process that releases energy from food in the presence of O2
Glycolysis
1 molecule of glucose is transformed into 2 molecules of pyruvic acid
Krebs cycle
pyruvic acid is broken down into CO2 in a series of reactions
Anaerobic
process that doesn’t require O2
Aerobic
process that requires O2
Fermentation
breakdown of organic molecules into energy in the absence of O2
Alcoholic fermentation
pyruvic acid is converted to ethyl alcohol and CO2 after glycolysis
Lactic acid fermentation
pyruvic acid converted into lactic acid after glycolysis
