Aerobic Cellular Respiration This reaction releases energy from the chemical bonds of carbohydrates (glucose). This is an aerobic process which means it requires oxygen.

takes place in the mitochondria Chemical equation: C6H12O6 + 6O2 6CO2 + 6H2O(38ATP)

Organisms that can do aerobic respiration: Plants Animals Fungi Protists Most bacteria ……basically anything alive!

Anaerobic Cellular Respiration (Fermentation) This is an anaerobic process which means that oxygen is not required. There are two types of fermentation: Alcohol Fermentation Lactic Acid Fermentation http://www.schmohz.com/images/beer-fermenter.jpeg

Alcohol Fermentation No oxygen present Produces 2 ATP, CO2, and alcohol

Organism that does alcohol fermentation Yeast The alcohol produced is the type that is consumed. The CO2 produced is used to make bread rise.

Lactic Acid Fermentation No oxygen present Produces 2 ATP, CO2, and lactic acid

Organisms that do lactic acid fermentation Humans (animals) – during exercise, our muscles don’t get enough O2 to keep up with demand. The build up of lactic acid makes your muscles start to burn.

Aerobic vs. anaerobic respiration You get much more ATP from aerobic cell respiration than you do from anaerobic (fermentation). Fermentation is used to provide organisms with a short-term supply of energy when oxygen is not available.
