2. Incomplete oxidation of glucose takes place to form alcohol / lactic acid and  CO 2  

3. It occurs in plant and animal cells

3. It occurs in anaerobic bacteria and                             human muscle cells 

4. For each molecule of glucose, 38 molecules of ATP are generated

4. For each molecule of glucose, only 2 molecules of ATP are generated 

Eg: Humans, Birds, Plants, Animals

Eg: Yeast, Muscle cells in human tissue, Archaebacteria, E. Coli and lactic acid bacteria
