Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which step(s) ONLY occur in aerobic respiration?
A
Glycolysis
B
Kreb cycle & Electron Transport Chain
C
Alcohol Fermentation
D
Lactic Acid Fermentation
Explanation: 

Detailed explanation-1: -The third step in aerobic respiration is the citric acid cycle, which is also called the Krebs cycle. In this stage of Aerobic respiration, the oxaloacetate combines with the acetyl-coenzyme A and produces citric acid.

Detailed explanation-2: -The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.

Detailed explanation-3: -In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.

Detailed explanation-4: -Krebs Cycle is a part of Cellular Respiration In aerobic respiration, oxygen is required. Cellular respiration is a four-stage process. In the process, glucose is oxidised to carbon dioxide and oxygen is reduced to water.

Detailed explanation-5: -Does Krebs cycle occur in anaerobic respiration? Though Krebs cycle doesn’t require oxygen it is exclusively an aerobic respiration method. In anaerobic respiration process, the first step is the same as the aerobic respiration process, that is glycolysis.
