Answer 1

The respiration which takes place without oxygen is called anaerobic respiration.It is called anaerobic respiration because it takes place without air which contains oxygen ('anaerobic' means 'without air').The microscopic organisms like yeast and some other bacteria obtain energy by anaerobic (which is in turn called fermentation).In anaerobic respiration,the micro-organisms like yeast breaks down the glucose (food) into ethanol and carbon dioxide, and release energy.this energy is then used by the micro-organisms. Anaerobic respiration produces much less energy which gets stored in the ATP molecules.
