Detailed explanation-1: -Respiration in the absence of oxygen is called anaerobic respiration . It is also termed fermentation. In this process, glucose is partially broken down anaerobically which produces two ATP. In bacteria, fermentation yield lactic acid.

Detailed explanation-2: -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. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation.

Detailed explanation-3: -Cellular respiration that proceeds without oxygen is called anaerobic respiration.

Detailed explanation-4: -Respiration is a chemical reaction which takes place in all livings cells and releases energy from glucose. Anaerobic respiration occurs without oxygen and releases less energy but more quickly than aerobic respiration. Anaerobic respiration in microorganisms is called fermentation.

Detailed explanation-5: -There are two types of Respiration: Aerobic Respiration-Takes place in the presence of oxygen. Anaerobic Respiration –Takes place in the absence of oxygen.
