A) amylase, maltase, zymase
B) diastase, maltase, zymase
C) amylase, invertase, zymase
D) amylase, zymase, maltase
Correct Answer: B
Solution :
The manufacture of ethyl alcohol from starch contains the following steps: (1) Hydrolysis of starch: \[2\,{{({{C}_{6}}{{H}_{10}}{{O}_{5}})}_{n}}+n{{H}_{2}}O\xrightarrow[50-{{60}^{o}}C]{diastase}\underset{maltose}{\mathop{n{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,\] This Step is called saccharification. (2) Fermentation: \[\underset{ethanol}{\mathop{2{{C}_{2}}{{H}_{5}}OH}}\,+2C{{O}_{2}}\]You need to login to perform this action.
