What is the anaerobic metabolic process that involves the conversion of organic substrates, such as carbohydrates, into simpler compounds through the action of enzymes?

Fermentation is an anaerobic process that produces chemical changes in organic substrates, leading to the production of simpler compounds like alcohol, lactic acid, and acetic acid. This process is widely used in the production of foods and beverages such as yogurt, cheese, beer, and wine.
