    In fermentation by zymase, alcohol and \[C{{O}_{2}}\]are obtained from

    A)  invert sugar      

    B)  glucose

    C)  fructose                             

    D)  All of these

    Correct Answer: B

    Solution :

                     In the fermentation of glucose by zymase, ethyl alcohol and \[C{{O}_{2}}\] is obtained. \[{{C}_{6}}{{H}_{12}}{{O}_{6}}\xrightarrow{zymase}\underset{ethyl\text{ }alcohol}{\mathop{2{{C}_{2}}{{H}_{5}}OH}}\,+2C{{O}_{2}}\uparrow \] Note - Fermentation is a process in which complex organic compounds are broken down into simple molecules by the action of biological catalysts known as enzymes. eg, \[\underset{sucrose}{\mathop{{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow{Invertase}\underset{glu\cos e}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,+\underset{fructose}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]
