   KEY CONCEPT 
     Fermentation allows the production of a small amount of ATP without oxygen.
      What is Fermentation?
  • Cellular respiration refers to a process by which cells 
   convert food into energy. 
  • Fermentation is a specific chemical reaction within 
   the respiration cycle. It takes place when the cells do 
   not have access to oxygen, a condition also known as 
   anaerobic respiration. 
  • The process of fermentation generates far less 
   energy than aerobic, or oxygen-based, respiration.
  Fermentation allows glycolysis to continue.
   • Fermentation allows glycolysis to continue 
    making ATP when oxygen is unavailable.
   • Fermentation is an anaerobic process.
    –occurs when oxygen is not available for cellular respiration
    –does not produce ATP
       • Fermentation allows glycolysis to continue making ATP when 
         oxygen is unavailable.
       •      +
          NAD is recycled to glycolysis 
       •  Lactic acid fermentation occurs in muscle cells.
           – glycolysis splits glucose into two pyruvate molecules
           – pyruvate and NADH enter fermentation
           – energy from NADH converts pyruvate into lactic acid
           – NADH is changed back into NAD+
         Fermentation and its products are 
                 important in several ways.
       • Alcoholic fermentation is similar to lactic acid 
         fermentation.
          –glycolysis splits glucose and the products enter fermentation
           – energy from NADH is used to split pyruvate into an alcohol and carbon dioxide
           – NADH is changed back into NAD+
           –      +
              NAD is recycled to glycolysis
