A) Invertase
B) Zymase
C) Dehydrogenase
D) Anolase
Correct Answer: B
Solution :
In yeast fermentation, the enzymatic reactions are as follows (1) \[{{C}_{12}}{{H}_{22}}{{O}_{11}}+{{H}_{2}}O\underset{\text{in yeast}}{\mathop{\xrightarrow{\text{Invertase}}}}\,\underset{\text{Glucose}}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,+\underset{\text{Fructose}}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] (2) \[{{C}_{6}}{{H}_{12}}{{O}_{6}}\underset{Yeast}{\mathop{\xrightarrow{\text{Zymase}}}}\,2{{C}_{2}}{{H}_{5}}OH\] \[+2C{{O}_{2}}+21\ kcal\ \text{energy}\].
