Respiration

• What is respiration?


  Respiration is the process by which we free the chemical energy stored in the food we eat so that we can use it for life processes such as movement growth and repwir
• what are the two types of respiration?

  aerobic-uses oxygen

  anaerobic-doesn’t use oxygen
• what is aerobic respiration?

  aerobic respiration is how living things usually release the energy they need
• what is the equation for aerobic respiration?

  oxygen+glucose~water+carbon dioxide
• What are the products of aerobic respiration?

  carbon dioxide and water
• Where does respiration take place?

  In the mitochondria
• What are two disadvantages of anaerobic respiration?

  it releases less energy and produces lactic acid which causes muscle cramps
• What is oxygen debt?

  the extra oxygen required after anaerobic respiration to break down lactic acid
• What form of respiration is fermentation most closely linked to and why?

  anaerobic respiration since it doesn’t require oxygen
• What happens when there is a limited amount of oxygen?

  A new form of respiration called anaerobic must be used
• what is the equation for anaerobic respiration?

  glucose~lactic acid
• why after exercise do we breathe heavily?

  the lactic acid produced needs oxygen to be broken down
• what are the main responses to increase the rate of respiration?

  -blood vessels

  -increase in breathing rate

  -increase in hear rate

  -increase in breath volume
• what is the by product of anaerobic respiration?

  lactic acid
• What does glucose break down into in anaerobic respiration?

  Lactic acid and energy
• what type of respiration is fermentation?

  anaerobic
• What does glucose break down into in fermentation?

  Carbon dioxide and ethanol
• what does lactic acid contain?

  carbon hydrogen and oxygen
• what is the site for respiration to occur?


  the inner membrane
• Word equation for fermentation?

  glucose~ethanol+carbon dioxide
