Exp:D Formation of alcohol by yeast is an anaerobic process, meaning it occurs in the absence of oxygen. It is also an extracellular process, as yeast cells release alcohol (ethanol) outside of their cell walls during fermentation. This process is indeed microbial, as it involves the activity of microorganisms like yeast. Hence, all of the above options are correct regarding the formation of alcohol by yeast.

Aerobic respiration produces more usable chemical energy than fermentation, because fermentation involves:
1 Formation of lactic acid
2 Complete oxidation of food
3 Partial oxidation of food
4 Evolution of $\mathrm{CO}_{2}$ and alcohol
Explanation:
Exp:C In aerobic respiration complete oxidation of food occur while in anaerobic respiration partial oxidation of food occur. Aerobic respiration are forms more usable chemical energy than fermentation. Number of ATP after aerobic respiration $=38$ ATP Number of ATP form after anaerobic respiration $=2$ ATP.

Alcoholic fermentation takes place in the presence of:
1 maltase
2 zymase
3 amylase
4 invertase
Explanation:
Exp:B Alcoholic fermentation takes place in the presence of zymase. Zymase is an enzyme complex that changes the simple sugars into ethanol and carbon dioxide. $\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6} \underset{\text { Yymase }}{\stackrel{\text { Yyast }}{\longrightarrow}} 2 \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+2 \mathrm{CO}_{2}$
Exp:B The process of fermentation occur during anaerobic respiration. In fermentation an organism like (yeast) converts carbohydrate into alcohol or acid. Yeast performs fermentation to obtain energy by converting sugar into alcohol. Lactic acid converts carbohydrates into lactic acid. $\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6} \longrightarrow 2 \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+2 \mathrm{CO}_{2}$
