Detailed explanation-1: -Glycolysis is the first step of both aerobic and anaerobic cellular respiration. During this process glucose is broken into two molecules and oxidized to form pyruvate.

Detailed explanation-2: -Similarities: The similarities between aerobic and anaerobic respiration, is that they both use glucose as the starting molecule. This is called the substrate. In addition, both aerobic and anaerobic respiration produce ATP, however, aerobic respiration produces a lot more ATP compared to anaerobic respiration.

Detailed explanation-3: -Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

Detailed explanation-4: -The process of aerobic respiration completely breaks down glucose into carbon dioxide and water, whereas anaerobic respiration incompletely breaks down glucose into alcohol (alcohol fermentation) or lactic acid (lactic acid fermentation).
