Based on this, we have two types respiration:

1. Aerobic respiration
2. Anaerobic respiration

Aerobic Respiration:
 The respiration which uses oxygen is called aerobic respiration.
 In aerobic respiration, the glucose food is completely broken down into carbon
dioxide and water by oxidation.
 Aerobic respiration produces a considerable amount of energy for use by the
organism which gets stored in the ATP molecules.

Anaerobic Respiration:
 The respiration which takes place without oxygen is called anaerobic
respiration.
 The microscopic organisms like yeast and some bacteria obtain energy by
anaerobic respiration (which is called fermentation).
 In anaerobic respiration, the microorganisms like yeast break down glucose
(food) into ethanol and carbon dioxide, and release energy.
 Anaerobic respiration produces much less energy which gets stored in the
ATP molecules.
