Detailed explanation-1: -Anaerobic respiration is a normal part of cellular respiration. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen.

Detailed explanation-2: -Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors.

Detailed explanation-3: -Anaerobic respiration only involves glycolysis. This step produces 2 ATPs and does not need any oxygen. The electron transport chain needs oxygen. Since anaerobic respiration only involves glycolysis (which is an anaerobic step itself) it does not need oxygen.

Detailed explanation-4: -The word anaerobic indicates “without oxygen.” The term has many uses in medicine. Anaerobic bacteria are germs that can survive and grow where there is no oxygen. For example, it can thrive in human tissue that is injured and does not have oxygen-rich blood flowing to it.
