Respiration

• what is the equation for aerobic respiration?


  C6H12O6 + 6O2 ➡️ 6CO2 + 6H2O
• what is the word equation for aerobic respiration?


  glucose + oxygen ➡️ carbon dioxide + water
• what is the formula equation for aerobic respiration? 


  .

  
• what is the equation formula for anaerobic respiration in yeast?


  .

  
• what is the word equation for anaerobic respiration in muscles/animal cells?


  glucose -> lactic acid
• what is the word equation for anaerobic respiration in yeast?


  glucose ➡️ alcohol + carbon dioxide
• do plants respire ALL the time?


  yes
• do plants photosynthesise ALL the time?


  no, only when there is sunlight
• what are the factors that affect rate of respiration?


  • temperature
  • pH
• where does aerobic respiration occur?


  in the mitochondria
• which chemical can be used to show that cells respire aerobically?

  limewater (turns cloudy in the presence of oxygen)
• does peristalsis require energy from respiration?


  yes
• what causes oxygen debt?


  lactic acid buildup in the muscles and blood during vigorous exercise when breathing anaerobically
• how does the body get rid of oxygen debt?


  • fast heart rate to transport lactic acid from the muscles to liver
  • deeper + faster breathing to supply oxygen
  • aerobic respiration of lactic acid in daliver
• why oxygen consumption does not immediately return to resting level after 


  • oxygen used to breakdown lactic acid from the muscles
  • heart rate continues to be high after exercise
  • as lactic acid combines with oxygen, oxygen is paid off
  • happens in daliver by aerobic respiration
  • fast heart rate helps transport lactic acid as quickly possible to muskce to liver
