Question

Enzymatic reactions are given in Column I and enzymes in Column II. Choose the correct matching of enzymatic reaction and enzyme that catalyses the correct reaction from the codes given below

• A. (a)-(ii), (b)-(iv), (c)-(v), (d)-(iii), (e)-(i)
• B. (a)-(iii), (b)-(iv), (c)-(i), (d)-(v), (e)-(ii)
• C. (a)-(v), (b)-(iv), (c)-(iii), (d)-(i), (e)-(ii)
• D. (a)-(v), (b)-(iii), (c)-(iv), (d)-(ii), (e)-(i)
• E. (a)-(ii), (b)-(iii), (c)-(i), (d)-(v), (e)-(iv)

Hint:

Remember key enzymes: Maltase → maltose, Invertase → sucrose, Zymase → fermentation, Diastase → starch, Pepsin → proteins

Answer 1

The Correct Option is B

Concept: Enzyme specificity and biochemical catalysis
Enzymes are highly specific biological catalysts. Each enzyme catalyzes a particular biochemical reaction. ---

Step 1: Match each reaction with its enzyme

• (a) Maltose $\rightarrow$ Glucose Maltase catalyzes hydrolysis of maltose into glucose \Rightarrow (a) $\rightarrow$ (iii)
• (b) Sucrose $\rightarrow$ Glucose + Fructose Invertase catalyzes hydrolysis of sucrose \Rightarrow (b) $\rightarrow$ (iv)
• (c) Glucose $\rightarrow$ Ethyl alcohol + CO$_2$ Zymase catalyzes fermentation \Rightarrow (c) $\rightarrow$ (i)
• (d) Starch $\rightarrow$ Maltose Diastase converts starch into maltose \Rightarrow (d) $\rightarrow$ (v)
• (e) Proteins $\rightarrow$ Amino acids Pepsin breaks proteins into peptides/amino acids \Rightarrow (e) $\rightarrow$ (ii) ---

Step 2: Final matching
\[ (a)-(iii), (b)-(iv), (c)-(i), (d)-(v), (e)-(ii) \] --- Final Answer: \[ \boxed{(B)} \]
