Krebs cycle (also known as Citric Acid Cycle or Tricarboxylic Acid Cycle) is a step wise cyclic process which is used to oxidize the pyruvate formed during the glycolytic breakdown of glucose into Carbon Dioxide (CO2) and Water (H2O). It also oxidizes acetyl CoA which arises from breakdown of carbohydrate, lipid, and protein. The actual Krebs cycle begins when acetyl –CoA enters into a reaction to form citric Acid. This cycle was discovered by British biochemist Sir Hans Krebs . For this he was awarded with Nobel Prize in 1953…..
