A) \[{{H}_{2}}O\] and \[C{{O}_{2}}\]
B) \[C{{O}_{2}}\]
C) alcohol and \[C{{O}_{2}}\],
D) alcohol
Correct Answer: C
Solution :
The end product of fermentation of sugars is alcohol and \[C{{O}_{2}}\]. Sugars are the most common substrate of fermentation, and typical examples of fermentation products are ethanol, lactic acid, and hydrogen. However, more exotic compounds can be produced by fermentation, such as butyric acid and acetone. Yeast carries out fermentation in the production of ethanol in beers, wines and other alcoholic drinks, along with the production of large quantities of carbon dioxide. Fermentation occurs in mammalian muscle during periods of intense exercise where oxygen supply becomes limited, resulting in the creation of lactic add.
