Differences and Similarities Aerobic and Anaerobic Respiration

Two Types of Anaerobic Respiration Lactic Acid Fermentation Reactants: Pyruvate and NADH Products: NAD+ and lactate (lactic acid) Occurs in Muscle cells and micro-organisms Alcohol Fermentation Reactants: Pyruvate Products: Ethanol and CO2 (waste) Occurs in Yeasts and some bacteria Aerobic Respiration Anaerobic Respiration Similarities Both processes begin with the breakdown of sugar (glucose) Both processes…
