Biology End of Term Exam revision (RESPIRATION T1)

TO REMEMBER:

  • Anaerobic=without oxygen
  • Aerobic=with oxygen
  • Oxygen debt is when the body uses more oxygen than it has, so you have to breathe deeper and more frequently to repay the oxygen you have taken
  • AEROBIC= glucosse+oxygen->carbon dioxide+water+ATP
  • C(6)0(6)H(12)=glucose
  • (6) O2=oxygen
  • (6)CO2=carbon dioxide
  • (6)H20=water
  • ATP=a form of enerygy used by our bodies

TYPES OF RESPIRATION

What is respiration? Respiration is the release of energy and other waste materials which can be used up or released from the body through absorbing glucose and oxygen into the mitochondria. There are two types of respiration: >aerobic >anaerobic

What is anaerobic respiration?Anaerobic resporation is when there is NO OXYGEN involved in the process of releasing waste materials. In this case, the waste material is lactic acid (along with a little bit of ATP). Lactic acid is poisonous to the body, which is why we have to breathe deeper and faster to transfer it into CO2 and H20 using the oxygen we are supplying. GLUCOSE->LACTIC ACID+(LITTLE AMOUNTS OF ATP)

What is aerobic respiration?Aerobic respiration INVLOVES OXYGEN in the reaction. It is MORE effective than anaerobic respiration due to higher amounts of energy being released and doesn't produce the poisonous LACTIC ACID. One disadvantage of aerobic respiration is that it REQUIRES OXYGEN at all times, which is difficult to have all the time

GLUCOSE+OXYGEN->CARBON DIOXIDE+WATER+ATP.
