Question

similarities and differences between aerobic and anaerobic respiration

Answer 1

Answer:

Similarities =)

• They both use glucose as the starting molecule. This is called the substrate.

• In addition, both aerobic and anaerobic respiration produce ATP, however, aerobic respiration produces a lot more ATP compared to anaerobic respiration.

Differences =)

• Aerobic respiration uses oxygen and is only completed when there is a plentifully supply of oxygen.

• Anaerobic respiration does not use oxygen, and so can be used when there is a small oxygen supply, so we can still produce some ATP, for example when completing vigorous exercise.

• In addition, the products of both reactions are different. Aerobic respiration produces carbon dioxide and water from the reaction (as well as the ATP).

• The word equation for this reaction is: Glucose + Oxygen --> Carbon Dioxide + Water (+ATP).

• On the other hand, anaerobic respiration only produces lactic acid, which can be harmful in large quantities and so has to be transported to the liver once it has been produced in order to be broken down.

• This means that after anaerobic respiration you have an oxygen debt, so need to keep breathing heavily, in order to allow aerobic respiration to begin again.

• Lactic acid also causes muscle fatigue, hence why after vigorous exercise you can experience pain or cramp.

• Therefore, the word equation for anaerobic respiration is: Glucose --> Lactic Acid

Answer 2

$\huge\tt { Answer - }$

$\huge]\tt\blue { Similarities-:}$

• Both aerobic and anaerobic respiration are necessary for the survival of living organism.

• In both type of respiration, the food is broken and energy is released for the functioning of an organism.

• In both type of respiration, carbon dioxide, water and energy is produced finally.

$\huge]\tt\blue {Differences -}$

• Aerobic respiration takes place using oxygen, inhaled in breathing.
• Anaerobic respiration requires no oxygen.

________________________________________

• Aerobic respiration uses respiratory organs such as lungs or gills.
• Anaerobic respiration takes place at cellular or muscular level.

___________________________________________

• In aerobic respiration, breakdown of glucose results in production of carbon dioxide,water and energy.
• In anaerobic respiration, breakdown of glucose first results in lactic acid and energy then lactic acid breakdown into carbon dioxide and water.
