    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. \[\underset{\begin{smallmatrix}  \text{Glucose}\,\text{and} \\  \text{fructose} \end{smallmatrix}}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\xrightarrow{Zymase}\underset{Ethanol}{\mathop{2{{C}_{2}}{{H}_{5}}OH}}\,+2C{{O}_{2}}\] Invertase enzyme converts sugar into glucose and fructose. \[\underset{Sugar}{\mathop{{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow{Invertase}\,\underset{Glu\cos e}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,+\underset{Fructose}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]
