Question

Match the terms in Column-I with their description in Column-II and choose the correct option:

Column I (Chemical reactions)		Column II (Enzymes used)
(i)	Glucose → CO2 + Ethanol	a	Pepsin
(ii)	Sucrose→Glucose + Fructose	b	Diastase
(iii)	Starch →Maltose	c	Zymase
(iv)	Protein→Amino acids	d	Invertase

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

Answer 1

The Correct Option is A

The question asks us to match chemical reactions in Column I with their corresponding enzymes in Column II. Let's go through each reaction and identify the correct enzyme involved:

1. Reaction (i): Glucose → CO₂ + Ethanol
   • This is a process of fermentation where glucose is converted to ethanol and carbon dioxide.
   • The enzyme responsible for this process is Zymase.

   Therefore, (i) matches with c.

2. Reaction (ii): Sucrose → Glucose + Fructose
   • This reaction involves the breakdown of sucrose into glucose and fructose, which is facilitated by the enzyme Invertase.

   Therefore, (ii) matches with d.

3. Reaction (iii): Starch → Maltose
   • Starch is broken down into maltose by the enzyme Diastase.

   Therefore, (iii) matches with b.

4. Reaction (iv): Protein → Amino acids
   • This is the hydrolysis of proteins into amino acids, which is carried out by the enzyme Pepsin.

   Therefore, (iv) matches with a.

By matching each reaction with its corresponding enzyme, the correct sequence of matches is:

i → c, ii → d, iii → b, iv → a

Thus, the correct option is i → c, ii → d, iii → b, iv → a.
