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

Detailed explanation-2: -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.

Detailed explanation-3: -Anaerobic respiration occurs without oxygen and releases less energy but more quickly than aerobic respiration. Anaerobic respiration in microorganisms is called fermentation.

Detailed explanation-4: -Aerobic respiration, a process that uses oxygen, and anaerobic respiration, a process that doesn’t use oxygen, are two forms of cellular respiration. Although some cells may engage in just one type of respiration, most cells use both types, depending on an organism’s needs.
