Respiration and combustion
respiration Combustion1.It is a biochemical process.1.It is a physiochemical process.2.It occurs in the living cells.2.It does not occur in the living cells.3.ATPisgenerated3.ATP is not generated4.Enzymes are required4.Enzymes are not requred5.It is a biologically−controlled process.5.It is an uncontrolled process.
Glycolysis and Krebs cycle
Glycolysis Krebs cycle1.It is a linear pathway1.It is cyclic pathway.2.It occurs in the cell cytoplasm.2.It occurs in the mitochondrial matrix.3.It occurs in both aerobic and3.It occurs in aerobic respiration. anaerobic respiration.4.It generates 2 NADH2 2 ATP4.It produces 6 NADH2,2FADH2,and 2 molecules on the breakdown of ATP molecules on the breakdown of two one glucose molecule.acetyl−CoA molecules.
Aerobic respiration and fermentation
Aerobic respiration Fermentation1.Oxygen is used for deriving energy1.Occurs in the absence of oxygen2.Occurs in the cytoplasm and2.Occurs in the cytoplasmmitochondria3.End products are carbon dioxide and water3.End products are ethyl alcohol andwatercarbon dioxide4.complete oxidation of the4.Incomplete oxidation of the respiratory substrate takes place respiratory substrate takes place5.About 36 ATP molecules are5.Only 2 ATP molecules are producedproduced
