anaerobic and aerobic respiration

Question 1

compare and contrast aerobic and anaerobic respiration

Answer 1

similarities - both use glucose, food is oxidised for energy production.

differences - aerobic requires oxygen, anaerobic does not. aerobic produces more energy.

Question 2

advantages and disadvantages of anaerobic respiration

Answer 2

useful for muscle cells when lungs and heart cannot deliver enough oxygen for aerobic respiration. respiration can continue in organisms with little to no oxygen present.

releases much less energy from glucose than aerobic. lactic acid is not removed and it builds up in muscles and the blood. it should be removed after excercise.

Question 3

uses of aerobic respiration

Answer 3

metabolic processes such as fatty acids to glycerol larger molecules are built from smaller

enables muscle contraction

steadys body temperature in animals
