Vedclass · Answer

(A) The commercial production of ethyl alcohol from starch involves three main enzymatic steps:$1$. Starch is converted to maltose by the enzyme $Diastase$ (found in germinated barley):$2(C_6H_{10}O_5)_n + nH_2O \xrightarrow{Diastase} nC_{12}H_{22}O_{11}$$2$. Maltose is converted to glucose by the enzyme $Maltase$ (found in yeast):$C_{12}H_{22}O_{11} + H_2O \xrightarrow{Maltase} 2C_6H_{12}O_6$$3$. Glucose is converted to ethyl alcohol by the enzyme $Zymase$ (found in yeast):$C_6H_{12}O_6 \xrightarrow{Zymase} 2C_2H_5OH + 2CO_2$Therefore,the correct sequence of enzymes is $Diastase$,$Maltase$,and $Zymase$.
