Sugars such as glucose are partially degraded without oxygen.
Among the three stages of cellular respiration, only glycolysis can produce ATP with or without oxygen.
To produce ATP, glycolysis couples with fermentation.
It starts with the consumption of pyruvate, which is the end-product of glycolysis. NAD, also another end-product during glycolysis, is recycled in fermentation.
What are the 2 types of fermentation?
Alcohol Fermentation
It occurs in bacteria and fungi such as yeast.
Pyruvate produced from glycolysis is converted into ethanol.
The end products are two ethanol and two carbon dioxide molecules for every glucose. Two ATP are also produced in the reaction.
Applications of Alcohol Fermentation
The process is commonly used to produce beer, wine, and other alcoholic beverages. Yeast, a fungus that undergoes alcoholic fermentation, is used to raise dough in making bread due to the production of carbon dioxide.
Lactic Acid Fermentation
It occurs to some bacteria, plants, and most animals.
Pyruvate is directly reduced by NADH to form lactate as a waste product.
The end products are two lactate molecules for every glucose. Two ATP are also produced in the reaction.
Applications of Lactic Acid Fermentation
Dairy products such as yogurt and cheese are produced by lactic acid fermentation.
There are two types of fermentation, alcoholic and lactic acid. Fermentation follows glycolysis in the absence of oxygen. Alcoholic fermentation produces ethanol, carbon dioxide, and NAD+. Lactic acid fermentation produces lactic acid (lactate) and NAD+
