Similarities and Differences Between Aerobic and Anaerobic Respiration

Answer:

Similarities: 

  • In both the processes the starting molecule used is glucose
  • Both the processes result in releasing of energy by breaking down food, and it takes place inside the cells of the body
  • Production of ATP (adenosine triphosphate) is also common in both processes

Differences: 

  • Presence of oxygen is an essential to aerobic respiration whereas absence of oxygen gives rise to anaerobic respiration
  • Absorption of oxygen and release of CO2 takes place in aerobic respiration. However, only some organisms release sulfur and nitrogen gasses during anaerobic respiration otherwise there is no exchange of gasses
  • Aerobic respiration produces 38 ATPs while anaerobic respiration produces only 2
  • Aerobic respiration is a longer process than anaerobic respiration
