Reverse Pasteur Effect
The reverse Pasteur effect is a phenomenon where the rate of fermentation increases as the rate of respiration increases. This effect occurs when cells transition from nearly anoxic to mild hypoxic oxygen concentrations take place. The reverse Pasteur effect is different from the Crabtree effect, which is when activated carbohydrate fermentation inhibits oxygen consumption. The Pasteur effect is when the rate of ethanol release decreases as the rate of respiration increases. The negative Pasteur effect is when alcoholic fermentation is inhibited under anaerobic conditions, but stimulated in the presence of molecular oxygen.
Pasteur Effect
The Pasteur effect is a phenomenon that occurs when oxygen slows down glycolysis in cells and suppresses lactate accumulation. The effect occurs in animal tissues and microorganisms. It also shows that in the presence of oxygen, cells shift from glycolysis to more efficient oxidative phosphorylation for ATP production. The Pasteur effect is important for preserving nutrients and increasing the energy yield per glucose molecule. In this article, we will study in detail the Pasteur effect, along with its mechanism and important applications.
