Controlled energy release from food without oxygen

Alternative name for anaerobic respiration

Fermentation

Where anaerobic respiration occurs in cell

Cytosol

Energy yield from anaerobic respiration

Small amount

Two types of fermentation

Lactic acid fermentation and alcohol fermentation

Lactic acid fermentation equation

Glucose → 2 lactic acid + small energy

Where lactic acid fermentation occurs in mammals

Muscle when short of oxygen

Effects of lactic acid buildup

Cramp and oxygen debt

Where lactic acid is broken down

Liver

Alcohol fermentation products

2 ethanol + 2 CO2CO_2 + small energy

Organism performing alcohol fermentation

Yeast (single celled fungus)

Alcohol fermentation use in brewing

Produces beer and wine

Alcohol fermentation use in baking

Makes bread rise

Why anaerobic respiration produces less energy

Glucose only partially broken down
