anaerobic respiration

• what is meant by anaerobic respiration


  respiration without using oxygen
• give examples of microorganisms that undergo anaerobic respiration


  yeast and clostridium perfringens
• what kind of aerobe is yeast


  facultative anaerobe
• give an example of animal tissue that may undergo anaerobic respiration


  muscle tissue
• in the absence of oxygen only glycolysis will occur , explain why


  there is no oxygen to act as the final electron acceptor in the electron transport chain
• why can the Krebs cycle and the link reaction not occur when there is no oxygen presnet


  because the reduced NAD cannot be reoxidised
• what process will not take place so that the yield of ATP produced by anaerobic respiration is reduced


  oxidative phosphorylation
• what is meant by oxidative phophorylation


  this is the process by which ATP is formed as a result of the electron transport chain
• what is the net gain of ATP from anaerobic respiration


  net gain of 2 ATP
• what is the gross of ATP produced from anaerobic respiration


  4
• why are 2 ATP molecules used in anaerobic respiration


  2 are used to phosphorylate glucose
• in the absence of oxygen what is needed for glycolysis to continue


  the regeneration of NAD
• what acts as the hydrogen acceptor in anaerobic respiration rather then oxygen


  pyruvate
