Question:

What are the differences between aerobic and anaerobic respiration? Name some organisms that use the anaerobic mode of respiration.

Answer:

 

Aerobic respiration

Anaerobic respiration

  1. In most of the plants and the animals, respiration occurs by the use of molecular oxygen and release of carbon dioxide, this phenomena is known as aerobic respiration.

 

  1. The organisms which carry aerobic respiration are known as aerobes.

  2. Gases are exchanged in this type of respiration.

 

  1. And, their metabolism occurs in cytoplasm or mitochondria.

  2. Glucose gets broken down into the carbon dioxide, water and energy is released in the form of ATP. It yields more energy available in glucose.

 

  1. Examples:- all higher organisms like mammals and plants, sponges, flatworms, roundworms etc. have this type of respiration. 

  1. In some organisms, respiration occurs without the use of molecular oxygen and it may or may not involve the production of carbon dioxide, this phenomena is known as anaerobic respiration.

  2. The organisms which carry anaerobic respiration are known as anaerobes.

  3. Gases are not exchanged in this type of respiration.

  4. Their metabolism occurs in only cytoplasm.

  5. In this glucose breaks down into ethyl alcohol and carbon dioxide without using oxygen, also known as alcoholic fermentation and lactic acid fermentation. And it yields only 5% energy available in glucose.

    Alcoholic fermentation or yeast oxidization:-

  6. Examples:- lower organisms like bacteria and yeast have this type of respiration. In bacteria, glucose breaks down into lactic acid and energy without the use of oxygen and without the production of carbon dioxide.
