Aerobic organism Aerotolerant organisms must continue fermentation in the presence of oxygen. A good example is the oxidation of glucose (a monosaccharide) in aerobic respiration. Oxygen is used during the oxidation of glucose and water is produced. This equation is a summary of what happens in three series of biochemical reactions: glycolysis, the Krebs cycle, and oxidative phosphorylation. Aerobic organism An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. In contrast, an anaerobic organism (anaerobe) is any organism that does not require oxygen for growth. Some anaerobes react negatively or even die if oxygen
