Distinguish between

Aerobic and anaerobic respiration.



  Aerobic Respiration Anaerobic respiration
i) It occurs in the presence of oxygen. It occurs in the absence of oxygen.
ii) It occurs via. three steps, namely, glycolysis, TCA cycle, and electron transfer chain It occurs via. two steps, namely, glycolysis and fermentation.
iii) The end products are CO2, H2O, and energy. The end products are organic acids or alcohol and energy.
iv) More amount of energy is generated. Less amount of energy is generated.
v) Complete oxidation of glucose takes place.  Incomplete oxidation of glucose takes place.
vi) It takes place in higher plants, animals, and certain aerobic microbes. It takes place in yeast, muscle cells, erythrocytes, and some anaerobic microbes.
