Section 3 Anaerobic Respiration Fermentation 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 (which does)

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)
