Unlike aerobic respiration, anaerobic respiration does not need oxygen. It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen.

Thanks for your questions

Explanation:

Answer 2

Answer:

• Anaerobic means without air (an means without). Respiration in the absence of oxygen to produce the energy they require this is called as  anaerobic respiration.
• Muscles need oxygen and glucose to respire aerobically and produce  the energy they require, these are carried to the muscle via the blood.  
• For vigorous exercise our heart and lungs would not be able to get sufficient oxygen to our muscles in order for them to respire. In this case muscles carry out anaerobic respiration.
• Glucose   ---->    Lactic acid + Energy
