1 Though the Krebs cycle does not directly require oxygen, it can only take place when oxygen is present because it relies on by-products from the electron transport chain, which requires oxygen. 2  The Krebs cycle is therefore an aerobic process.
Krebs cycle. is the 2nd stageof cellular respiration. (glycolysis is the 1st stage). During the Krebs cycle, pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions. The Krebs cycle is also known as the. citric acid cycle. , because citric acid is one of its 1st products.The Krebs cycle starts when pyruvic acid formed by glycolysis enters the mitochondrion. The pyruvic acid is broken down into carbon dioxide and a 2-carbon acetyl group. The 2 carbons of the acetyl group join a 4-carbon compound to produce citric acid.The Krebs cycle continues in a series of reactions.rebs cycle. is the 2nd stageof cellular respiration.
