What is the anaerobic process, carried out by yeast, that converts sugar into alcohol and carbon dioxide?

Explanation

Fermentation is an anaerobic, meaning oxygen-free, process in which microorganisms like yeast convert sugars into alcohol and carbon dioxide, or in some cases into other products like lactic acid. This process is essential for producing bread, where the carbon dioxide released causes dough to rise, as well as for producing alcoholic beverages. Fermentation has been used by humans for thousands of years, long before the underlying chemistry was understood scientifically. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
