The majority of glycolytic pathway reactions are reversible, which is essential for gluconeogenesis or the formation of new glucose. 10 terms. In the absence of oxygen, the Krebs cycle is not active and acid and pyruvate can quickly accumulate. On the other hand, Kreb cycle or citric acid cycle involves the oxidation of acetyl CoA into CO2 and H2O.. Respiration is the important process of all the living being, where oxygen is utilised and carbon dioxide is released from the body. In its most simple form glucose can be thought of as a 6 carbon molecule. OK. in the presence of O2, it is converted to acetyl CoA, which enters the citric acid cycle the citric acid cycle oxidizes two-carbon units, producing 2 molecules of CO2, one molecule of ATP and high-transfer-potential electrons It is important to remember that this pathway is only the first section of a larger process (metabolism), as Pyruvate from this chain is used later in Krebs cycle etc. Glycolysis is the metabolic pathway that converts glucose C6H12O6, into pyruvate, CH3COCOO (pyruvic acid), and a hydrogen ion, H .
