Chapter 8 Section 3 Anaerobic Respiration Fermentation
Anaerobic Respiration • Anaerobic Respiration Requires NO Oxygen! • Organisms that use only anaerobic respiration include: • Prokaryotic: Bacteria, Yeast • Eukaryotic: Some Fungi, Many aquatic invertebrates
Anaerobic Respiration • The anaerobic pathway that follows glycolysis is called FERMENTATION • It occurs in the CYTOPLASM and regenerates the carrier molecules, which allow glycolysis to loop.
Two main types of fermentation • Lactic acid fermentation • Alcohol fermentation
Lactic acid fermentation • The PYRUVATE made during glycolysis is converted to lactic acid. • Although it produces no ATP, this process replenishes the carrier molecules required to run glycolysis
Alcohol fermentation • The PYRUAVTE made during glycolysis is converted to ethyl alcohol by releasing a molecule of CARBON DIOXIDE. • Although it produces no ATP, this process replenishes the carrier molecules required to run glycolysis (which does)
