Ethanol, the type of alcohol found in beverages and used in hand sanitizers, is commonly produced through which biological process?
AElectrolysis of salt water
BFermentation of sugars by yeast
CDistillation of water
DCombustion of hydrocarbons
Explanation
Ethanol is commonly produced through fermentation, a biological process in which yeast converts sugars from sources like grains, fruits, or sugarcane into ethanol and carbon dioxide in the absence of oxygen. This same underlying chemical process is used to produce alcoholic beverages as well as industrial ethanol used in products like hand sanitizers and fuel additives. Fermented mixtures are often further concentrated afterward using distillation to increase the ethanol content. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
