Answer 2

The characteristic processes observed in anaerobic respiration are c) ii), iii), iv) only

• Anaerobic respiration doesn't involves the presence of oxygen to occur. The word anaerobic itself means absence of oxygen. Hence, i) is wrong option.
• During the anaerobic respiration lactic acid is formed. This can be seen as a common example when the muscles get fatigued after a hectic workout or exercise.
• After lactic acid formation , it reacts with the oxygen to form carbon dioxide and energy release takes place.
• The release of energy in anaerobic respiration is generally rapid then aerobic respiration. However, it's for a very less time.
• Hence, correct option is c) ii), iii), iv) only
