Respiration | Combustion |
1. It takes place in living cells only. | 1. It does not take place in the living cell. |
2. It is carried out with the help of various enzymes. | 2. Enzymes are not involved in this process. |
3. The oxidation of food and the liberation of energy occur in a step-wise manner. | 3. The substances are oxidized spontaneously with sudden release of energy. |
4. It occurs at the body temperature of the organism. | 4. Sudden release of energy generates high temperature of a fire. |
5. 60% of energy escapes as body heat and 40% of energy is packaged directly into new chemical energy (ATP). | 5. Energy released in combustion is dissipated as heat and to some extent as light. |
Glycolysis | Krebs cycle |
1. It is a linear pathway. | 1. It is a cyclic pathway. |
2. It occurs in the cell cytoplasm. | 2. It occurs in the mitochondrial matrix. |
3. It occurs in both aerobic as well as anaerobic respiration. | 3. It occurs in aerobic respiration only. |
4. Net generation of 2 and 2 ATP molecules occurs on the breakdown of one glucose molecule. | 4. It produces 6 , 2FADH, and 2 ATP molecules on the breakdown of two acetyl-CoA molecules generated after glycolysis of one glucose molecule. |
Aerobic respiration | Fermentation |
1. Oxygen is used for deriving energy. | 1. Occurs in the absence of oxygen. |
2. Occurs in the cytoplasm and mitochondria. | 2. Occurs in the cytoplasm. |
3. End products are carbon dioxide and water. | 3. End products are ethyl alcohol and carbon dioxide. |
4. Complete oxidation of the respiratory substrate takes place. | 4. Incomplete oxidation of the respiratory substrate takes place. |
5. About 36 ATP molecules are produced. | 5. Only 2 ATP molecules are produced. |
Step | Site of occurrence |
Glycolysis | Cytoplasm |
Kreb's cycle | Matrix of mitochondria |
Electron transport system | Inner mitochondrial membrane |
Oxidative phosphorylation | F0 - F1 particles in the inner mitochondrial membrane |
Aerobic Respiration | Anaerobic Respiration |
1. Aerobic respiration takes place in the presence of free oxygen. | 1. Anaerobic respiration takes place in the absence of free oxygen. |
2. The first step of this process (glycolysis) takes place in the cytoplasm while the second step (Krebs cycle) is carried out in mitochondria. | 2.The complete process is carried out outside the mitochondria i.e., in the cytoplasm. |
3. Glucose is completely oxidized into carbon dioxide and water. | 3. Glucose is incompletely oxidized into carbon dioxide and ethyl alcohol. |
4. 38 molecules of ATP are produced by the complete oxidation of one gram-mole of glucose. | 4. Only 2 molecules of ATP are formed in this process. |
Glycolysis | Fermentation |
1. Glycolysis is a common process during aerobic and anaerobic respiration. | 1. Fermentation is a type of anaerobic respiration. |
2. Pyruvic acid is produced as its end product. | 2. Ethanol or lactic acid is produced as its end product. |
Glycolysis | Citric acid cycle (Krebs cycle) |
1. It is a linear pathway. | 1. It is a cyclic pathway. |
2. It occurs in the cell cytoplasm. | 2. It occurs in the mitochondrial matrix. |
3. It occurs in both aerobic as well as in anaerobic respiration. | 3. It occurs in aerobic respiration only. |
4. One glucose molecule breaks down to generate 2 NADH22 and 2 ATP molecules. | 4. It produces 6 NADH22, 2 FADH22, and 2 ATP molecules on the breakdown of two acetyl-CoA molecules generated after glycolysis. |
