Aerobic respiration “with oxygen” Anaerobic respiration “without oxygen” Anaerobic respiration is fermentation Some organisms can only use fermentation (obligate anaerobes) Some will undergo aerobic if oxygen is present, but anaerobic if it is not (facultative anaerobes)

Some organisms require aerobic respiration, but have specialized CELLS that can undergo anaerobic EX: Humans and their muscle cells

Fermentation Anaerobic process by which pyruvate is converted into another molecule in order to regenerate NAD+ 2 kinds Alcoholic fermentation Lactic acid fermentation
