WebApr 21, 2024 · Glycolysis and pentose phosphate pathway are ubiquitous in all domains of life. Glycolytic pathway is an anaerobic pathway and does not require oxygen essentially for conversion of glucose to pyruvate. However, glycolysis is categorized as aerobic or anaerobic depending upon the oxidation of NADH generated during glycolysis. WebThe Krebs cycle starts with pyruvic acid from glycolysis. Each small circle in the diagram represents one carbon atom. For example, citric acid is a six carbon molecule, and OAA (oxaloacetate) is a four carbon molecule.
