Hint: Both are cellular respiration that occurs in the cell of an organism where one process occurs in the presence of oxygen while the others do not and results in the formation of the ATP in the form of energy.
Aerobic respiration requires oxygen where carbohydrates are oxidized to produce water and carbon dioxide. During anaerobic respiration, no oxygen is required and the fold undergoes incomplete oxidation resulting in the production of carbon dioxide.
-Energy is produced in the form of ATP in aerobic respiration.
-It mostly occurs in the cell cytoplasm and then to the mitochondria.
-There are various processes that come under aerobic respiration: glycolysis, oxidative decarboxylation of pyruvate, and citric acid cycle.
-Glycolysis occurs in the cytoplasm where the glucose molecule is broken down to form pyruvate molecules.
-The oxidation of pyruvate molecules occurs in the mitochondria resulting in the process called oxidative decarboxylation of pyruvate.
-The pyruvate after oxidation will produce acetyl Co-A.
-The acetyl Co-A may undergo aerobic or anaerobic respiration depending upon the conditions.
-During anaerobic respiration, the oxygen is not accepted instead electrons are used.
-Anaerobic respiration is of two types: cellular respiration, and fermentation.
-Both the process of anaerobic respiration will produce energy and also the electrochemical potential gradient across the cell membrane.
So, the correct answer is ‘Both A and B'.
Note: The aerobic respiration is explained well in the Krebs cycle which was discovered by a German biochemist Hans Kreb. The anaerobic respiration comes first from which the aerobic respiration was evolved. The possibility of anaerobic respiration was suggested by Louis Pasteur. The anaerobic respiration was first discovered and described by Beijerinck in 1895.
