Question

Regarding the digestion of carbohydrates; Match the following intermediates with the particular enzyme:
$\begin{array}{cc}\text{Column I (Enzyme)}& \text{Column II (Substrate)}\\ \text{i. Amylase}& \text{a. Maltose.}\\ \text{ii. Maltase}& \text{b.Saccharides.}\\ \text{iii.Sucrase}& \text{c.Dextrins.}\\ \text{iv.}\alpha \text{Dextrinase}& \text{d.Sucrose.}\end{array}$

• A. i).➡ c., ii).➡ d., iii).➡ d., iv). ➡ a..
• B. i).➡ b., ii).➡ a., iii).➡ d., iv). ➡ c..
• C. i).➡ d., ii).➡ b., iii).➡ a., iv). ➡ c..
• D. i).➡ a., ii).➡ c., iii).➡ b., iv). ➡ d..

Answer 1

The correct option is B

i).➡ b., ii).➡ a., iii).➡ d., iv). ➡ c..

The correct matching pairs are :
$\begin{array}{cc}ColumnI\left(Enzyme\right)& ColumnII\left(Substrate\right)\\ i.Amylase& b.Saccharides.\\ ii.Maltase& a.Maltose.\\ iii.Sucrase& c.Sucrose.\\ iv.\alpha Dextrinase& d.Dextrins.\end{array}$
So the correct option is B. $\to$ i).$\to$ b., ii).$\to$ a., iii).$\to$ c., iv). $\to$ d..
The substrate is a molecule upon which an enzyme acts. Enzymes catalyse chemical reactions involving the substrate.
