1. Krebs cycle is the main center of energy production. This energy is used in various metabolic functions – mineral salt absorption, water absorption, transport, movement, growth, flowering etc.
2. α-ketoglutaric acid and oxaloacetic acid produced in this cycle help in nitrogen metabolism.
3. This process involves the production of amino acids.
4. Various types of organic acids produced in this cycle are used in metabolism.
5. In this cycle succinyl CO is produced. Succinyl Co-A is one of the building blocks of chlorophyll, cytochrome, hemoglobin, phycobilin etc.
6. Organisms release CO2 through this cycle.
7. Each molecule of glucose oxidized produces 24 ATP.
8. Pyrimidines and alkaloids are produced from oxaloacetic acid.
9. Oxidation of carbohydrates, fatty acids and amino acids occurs through the Krebs cycle.
10. Oxidative co-enzymes NADH+H+ and FADH2 are synthesized through the Krebs cycle.
11. This cycle links sugar metabolism with nitrogen metabolism.
12. This cycle is called amphibolic pathway as both addition and dissociation reactions occur.
13. This cycle is linked to the glyoxylate cycle.
