1) Anaerobic respiration is less efficient than the aerobic respiration.
2) Limited number of ATP molecules is generated per glucose molecule
3) It is characterized by the production of CO₂ and it is used for Carbon fixation in photosynthesis.

1) Alcoholic fermentation
2) Lactic acid fermentation
3) Mixed acid fennenatation.

The first pathway of respiration Glycolysis was worked out by three scientists. Embden, Meyerhoff and pamas. Hence it is also called EMP pathway.

At night time plants take oxygen and release carbon di oxide. As a result carbon di oxide will be abundant around the tree. In the night plants only respire. Photosynthesis does not take place by which oxygen can be released.

Glycolysis .pathway of respiration is common to all living organisms (aerobic and anaerobic). It occurs in the cytoplasm of the cell. In Glycolysis, one molecule of glucose is converted into two molecules of pyruvic acid.
