key concept fermentation allows the production of a small amount of atp without oxygen
DESCRIPTION
KEY CONCEPT Fermentation allows the production of a small amount of ATP without oxygen. Fermentation allows Glycolysis to continue making ATP when oxygen is unavailable . Anaerobic process Glycolysis will happen the same way it does at the beginning of cellular respiration - PowerPoint PPT PresentationTRANSCRIPT

4.6 Fermentation
• Fermentation allows Glycolysis to continue making ATP when oxygen is unavailable.• Anaerobic process
• Glycolysis will happen the same way it does at the beginning of cellular respiration– Glycolysis splits glucose into two pyruvic acid molecules– Pyruvic acid and NADH enter Fermentation

4.6 Fermentation
• Fermentation will occur instead of cellular respiration due to the lack of oxygen
• Occurs in the cytoplasm of cells• Fermentation does not produce ATP

4.6 Fermentation
Two Types of Fermentation• Lactic Acid• Alcoholic

4.6 Fermentation
• Lactic acid fermentation • occurs in animal muscles when the tissue requires
energy at a faster rate than oxygen can be supplied• used to convert lactose into lactic acid in yogurt and
cheese production• also gives the sour taste to fermented vegetables such
as pickles

4.6 Fermentation
• Alcoholic fermentation – Yeast and certain bacteria– Pyruvate is broken into alcohol and carbon dioxide– Used in the production of beer, wine and bread

Uses of fermentation in industry• Sewage treatment• Biofuels• Hydrogen gas
