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

Detailed explanation-1: -Glycolysis is a common step for both aerobic and anaerobic respiration . It takes place in the cytoplasm and is independant of the presence or absence of oxygen. Two molecules of pyruvic acid/pyruvate is formed as the end product of glycolysis.

Detailed explanation-2: -Glycolysis occurs in both aerobic and anaerobic states. 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.

Detailed explanation-3: -In addition, both aerobic and anaerobic respiration produce ATP, however, aerobic respiration produces a lot more ATP compared to anaerobic respiration. Food is oxidized in both cases and energy is released.
