Detailed explanation-1: -Aerobic Respiration-Takes place in the presence of oxygen. Anaerobic Respiration –Takes place in the absence of oxygen.
Detailed explanation-2: -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. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.
Detailed explanation-3: -The breakdown of glucose occurs in the cells of an organism (cellular respiration). If the food is broken down with the use of oxygen, it is called aerobic respiration. If the breakdown occurs without the use of oxygen, the respiration is called anaerobic respiration.
