Question

Ravi mixed yeast to sugar solution . What changes may be observed by him?

Answer 1

Answer:

OBSERVATION OF RAVI -

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'
