Detailed explanation-1: -Glycolysis does not require oxygen.
Detailed explanation-2: -Glycolysis does not require oxygen and occurs during both aerobic and anaerobic respiration. If there is oxygen available, aerobic respiration can occur and the pyruvate molecules produced at the end of glycolysis will be transported to the mitochondria to enter the citric acid cycle.
Detailed explanation-3: -The first stage of cellular respiration is glycolysis. It does not require oxygen, and it does not take place in the mitochondrion-it takes place in the cytosol of the cytoplasm.
Detailed explanation-4: -Aerobic glycolysis is a series of reactions wherein oxygen is required to reoxidize NADH to NAD+, hence the name. This ten-step process begins with a molecule of glucose and ends up with two molecules of pyruvate[1].
Detailed explanation-5: -The correct answer is e. The statement regarding glycolysis which is true is oxygen is not required. In the process of glycolysis, oxygen is not required because it is an anaerobic process that is independent of oxygen.
