The energy - releasing metabolic process in which substrate is oxidise...
In fermentation, the incomplete oxidation of glucose is achieved under anaerobic conditions by a set of reactions, where pyruvic acid is converted to CO2 and ethanol. The enzyme pyruvic acid, decarboxylase and alcohol dehydrogenase catalyse these reactions. In animals cells also, like muscles during exercise, where oxygen is inadequate for cellular respiration, pyruvic acid is reduced to lactic acid by lactate dehydrogenase. The reducing agent is NADH + H+, which is reoxidized to NAD+, in both the processes.

Fermentation
Fermentation is a type of energy-releasing metabolic process in which substrate is oxidized without an external electron acceptor. It is a process that occurs in the absence of oxygen or other external electron acceptors.
Types of Fermentation
There are two types of fermentation:
1. Alcoholic Fermentation: In alcoholic fermentation, glucose is converted into ethanol and carbon dioxide. This process is carried out by yeast and some bacteria. Alcoholic fermentation is used in the production of alcoholic beverages such as beer and wine.
2. Lactic Acid Fermentation: In lactic acid fermentation, glucose is converted into lactic acid. This process is carried out by some bacteria and muscle cells during strenuous exercise when there is not enough oxygen available for aerobic respiration.
Importance of Fermentation
Fermentation is an important metabolic process because it allows cells to generate energy in the absence of oxygen. It is also used in the production of many food products such as bread, cheese, and yogurt.
