A) invertase, diastase
B) invertase, zymase
C) zymase, diastase
D) invertase, maltase
Correct Answer: B
Solution :
Diastase enzyme is present in barley and it converts starch into maltose. The reactions are: \[\underset{\text{Sucrose}}{\mathop{{{C}_{6}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow[(Yeast)]{\text{Invertasse}}\underset{\text{Fructose}}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] \[\underset{\text{Fructose}}{\mathop{+{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] \[\underset{\begin{smallmatrix} \text{Glucoe}\, \\ \text{Fructose} \end{smallmatrix}}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\xrightarrow[(Yeast)]{Zymase}2{{C}_{2}}{{H}_{5}}OH+2C{{O}_{2}}\] So, to convert sucrose into \[{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}\text{.}\]invertase and zymase enzymes are required which are present in yeast.You need to login to perform this action.
