    Which enzyme converts glucose into alcohol?

    A)  Zymase                              

    B)  Diastase

    C)  Invertase                           

    D)  Lipase

    Correct Answer: A

    Solution :

    Glucose and fructose are both converted to       ethanol and carbon dioxide in presence of zymase          enzyme.             \[\underset{\begin{smallmatrix}  \text{Glucose}\,\text{and} \\  \text{fructose} \end{smallmatrix}}{\mathop{{{\text{C}}_{\text{6}}}{{\text{H}}_{\text{12}}}{{\text{O}}_{\text{6}}}}}\,\xrightarrow{\text{Zymase}}\underset{\text{Ethanol}}{\mathop{\text{2}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH+2C}{{\text{O}}_{\text{2}}}}}\,\]             In vertase enzyme converts sugar into glucose and              fructose.             \[\underset{\begin{smallmatrix}  \text{Sugar} \\  \text{+}{{\text{C}}_{\text{6}}}{{\text{H}}_{\text{12}}}{{\text{O}}_{\text{6}}}  \\  \text{Fructose} \end{smallmatrix}}{\mathop{{{\text{C}}_{\text{12}}}{{\text{H}}_{\text{22}}}{{\text{O}}_{\text{11}}}\text{ }\!\!\_\!\!\text{ }{{\text{H}}_{\text{2}}}\text{O}}}\,\xrightarrow{\text{Invertase}}\underset{\text{Glucose}}{\mathop{{{\text{C}}_{\text{6}}}{{\text{H}}_{\text{12}}}{{\text{O}}_{\text{12}}}{{\text{O}}_{\text{6}}}}}\,\]
