A) high concentration of sugar solution, low temperature and plenty of air
B) low concentration of sugar solution high temperature and absence of air
C) low concentration of sugar solution low temperature and plenty of air supply
D) high concentration of sugar solution low temperature and absence of air
Correct Answer: C
Solution :
Fermentation is the process of bio-decomposition of a compound. Sugar (glucose), on fermentation gives alcohol and carbon-dioxide. Yeast is added to the dilute sugar solution to provide enzyme Zymase, required for the reaction. Plenty of air and low temperature are essential for the process. \[{{C}_{6}}{{H}_{12}}{{O}_{6}}\xrightarrow{Zymase}2{{C}_{2}}{{H}_{5}}OH+2C{{O}_{2}}\uparrow \]
