Question

________ is added to the sugar solution in the process of fermentation.​

Answer 1

Answer:

When yeast has both sugar and oxygen available to it, it undergoes aerobic respiration to produce energy, water and carbon dioxide. In the absence of oxygen, yeast switches over to a process called anaerobic respiration during which, sugar is fermented to produce energy, carbon dioxide, and ethanol. Yeast that produces ethanol from the sugar has a characteristic smell and this process is generally used to ferment wine.

So, the correct answer is 'Ethanol'.

Answer 2

Answer:

Fermentation is the reaction that is used to produce alcohol from sugar. It is an anaerobic reaction, which means it requires no oxygen to be present other than the oxygen atoms contained in the sugar. ... The other ingredient required for the reaction to take place is yeast.
