Detailed explanation-1: -Glycolysis occurs in both aerobic and anaerobic states.
Detailed explanation-2: -Glycolysis is not dependent on the presence of oxygen and can occur in either aerobic or anaerobic environments. The citric acid cycle, or Krebs cycle, is used to generate NADH from pyruvate. The NADH is then used in the electron transport chain to generate a proton gradient, which fuels oxidative phosphorylation.
Detailed explanation-3: -(i) In aerobic respiration, glycolysis occurs in the cytoplasm of a cell. (ii) In aerobic respiration, glycolysis cannot occur without the presence of oxygen. (iii) In the process of glycolysis, glucose molecules are oxidised to produce the molecules of pyruvate.
Detailed explanation-4: -Glycolysis is common to both aerobic and anaerobic respiration because glucose is the only source of energy and the process of glycolysis is independent of oxygen. Thus, the absence or presence of oxygen does not play a role in this process which is common to both aerobic and anaerobic respiration.
