respiration

• define what respiration is 


  the process by which chemical energy stored in glucose is released
• how is ATP linked to ADP + Pi?


  ATP is made form 1 adenosine + 3 inorganic phosphate (Pi) groups
• Give examples of where ATP is required in the body 


  cell division, muscle cell contraction
• what is the number of ATP produced from glucose --> pyruvate breakdown?


  2 ATP
• what is one glucose broken down to?

  2 pyruvate
• when does fermentation occur?

  when oxygen is not present
• what are the products of fermentation in animal cells?


  lactate and 2 ATP
• what are the products of fermentation in plant (and yeast) cells?


  Ethanol and carbon dioxide.
• what 3 different between aerobic respiration and fermentation?


  Aerobic respiration requires oxygen and fermentation does not. fermentation produces 2 ATP and aerobic respiration produces a large number of ATP. Aerobic respiration produces carbon dioxide, water and energy however fermentation produces lactate (animal cells one)
• where does fermentation occur?


  in the cytoplasm
• where does aerobic respiration occur?


  in the mitochondria
