Anaerobic Respiration

Fermentation: the anaerobic respiration that follows glycolysis ATP is made in the absence of oxygen Occurs in the cytoplasm of cells

Occurs in some prokaryotes They grow and reproduce without oxygen

Another form can occur in certain eukaryote cells

Two Main Types of Fermentation: Lactic Acid Fermentation Alcohol Fermentation

Lactic Acid Fermentation Enzymes convert the pyruvic acid made during glycolysis into lactic acid (a different molecule) Muscle cells produce lactic acid when the lungs and blood stream cannot keep up with the muscles’ need for ATP

Causes the burn and fatigue that you feel while working out

Lactic Acid Some microorganisms produce lactic acid that is used in making dairy products

Alcohol Fermentation Pyruvic acid is converted to ethyl alcohol and carbon dioxide This occurs in yeast and some bacteria Used for making bread and some forms of alcohol
