Compare and contrast aerobic and anaerobic reactants

One of the similarities between aerobic and anaerobic respiration is that they both use glucose as the initial molecule, which is called the substrate. Moreover, both aerobic and anaerobic respiration produce Adenosine 5'-triphosphate (ATP), however, aerobic respiration produces more ATP compared to anaerobic respiration. Which actually means that glucose goes through dissimilar processes in anaerobic and aerobic respiration, therefore producing a different amount of ATP. Aerobic respiration uses oxygen and is only done when there is an abundant supply of oxygen. On the contrary, anaerobic respiration does not use oxygen, therefore it can be used even with a small supply of oxygen, hence we can still produce some ATP, for example when doing a strenuous exercise. Additionally, the products of both reactions are not the same. Aerobic respiration produces water and carbon dioxide from the reaction. On the other hand, anaerobic respiration produces lactic acid only, that can be harmful in large amounts, that is why it has to go to the liver once it has been produced so that it will be broken down.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

halogen, any of the six nonmetallic elements that constitute group 17 (group viia) of the periodic table. the halogen elements are fluorine (f), chlorine (cl), bromine (br), iodine (i), astatine (at), and tennessine (ts).
