Question

The end product of fermentation when sugar is used as raw materials is/are?
A. Alcohol and ${ CO }_{ 2 }$
B. Alcohol and pyruvate
C. ${ CO }_{ 2 }$
D. Alcohol

Answer 1

Hint: A toxic drink produced by chemically breaking fruit or grain sugar and heat releases in this process.

Complete step-by-step answer:
Fermentation is the process of breaking down sugar substances by chemical means involving microorganisms and releasing heat. The end products of fermentation are alcohol and carbon dioxide.

Additional information:
-In fermentation, the chemical will change into organic substances by certain enzymes.
-In this process, in the absence of oxygen energy is obtained from various carbohydrates.
-It is used in the production of various food and beverages.
-This process also occurs inside the gastrointestinal tracts of humans and many animals.
-During the process of fermentation, one molecule of glucose will form two molecules of ethanol and two molecules of carbon dioxide.
-It is used commonly in the production of the making of bread, beer, wine, etc.
-The process of fermentation has been used for a longer time, since the Neolithic age.
-In rumens of cattle, fermentative bacteria are present which helps in the production of methane.

So, the correct answer is ‘Alcohol and ${ CO }_{ 2 }$'.

Note: Fermentation is of significant importance for long. The people worshipped Baltic god Rugutis as the agent of fermentation. Louis Pasteur repeated Schwann's experiments during the 1850s and 1860s to show that fermentation occurs in living organisms, which he later named as lactic acid fermentation. In 1897, Edward Buechner used yeast to form end products of fermentation. He was awarded the Nobel Prize in chemistry for this.
