The anaerobic … ♦ Saturated and Unsaturated What does this sentence mean? Where does glycolysis occur? In this process, glucose undergoes partial oxidation to form two molecules of pyruvic acid. The last step in glycolysis will not occur if pyruvate kinase, the enzyme that catalyzes the formation of pyruvate, is not available in sufficient quantities. How are dietary fat classified? A phosphate group is added to the glucose molecule by the enzyme hexokinase, producing glucose 6-phosphate. Owing to its inevitability, glycolysis can occur both in the presence and in the absence of oxygen. Glycolysis takes place in the cytoplasm and can happen aerobically or anaerobically—that is, with or without oxygen (aero– is from the Greek meaning "air," while an– means "without").
