Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the main difference between aerobic and anaerobic respiration?
A
Aerobic uses oxygen and produces a total of 2 ATP, anaerobic does not require oxygen and produces 38 ATP molecules
B
Aerobic respiration uses the process of glycolysis, while anaerobic does not.
C
Aerobic uses oxygen and produces 38 ATP molecules, while anaerobic does not require oxygen and produces 2 ATP molecules
D
Anaerobic respiration uses the process of glycolysis, while aerobic does not.
Explanation: 

Detailed explanation-1: -Aerobic respiration uses oxygen. Anaerobic respiration is respiration without oxygen; the process uses a respiratory electron transport chain but does not use oxygen as the electron acceptors.

Detailed explanation-2: -Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.

Detailed explanation-3: -The citric acid cycle produces 36 ATP molecules. So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria.

Detailed explanation-4: -Aerobic respiration needs oxygen to occur, while anaerobic does not. This presence of oxygen determines what products will be created. During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created.

Detailed explanation-5: -In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the net production of 32 ATP molecules. In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis. Anaerobic respiration results in the production of 2 ATP molecules.
