Question

Match the LIST I (Enzyme) with LIST II (Catabolic Products) 

LIST-I		LIST-II
(Enzyme)		(Catabolic Products)
A	\(\beta\)-galactosidase	III	Galactose + glucose
B	Lecithinase	I	Choline + H$_3$PO$_4$ + fat
C	Urease	IV	CO$_2$ + NH$_3$
D	Lipase	II	Glycerol + fatty acids

• A. A - III, B - IV, C - I, D - II
• B. A - III, B - I, C - IV, D - II
• C. A - III, B - II, C - IV, D - I
• D. A - II, B - I, C - IV, D - III

Hint:

The names of enzymes often indicate their substrate: \(\beta\)-galacto\textbf{sidase} acts on a galacto\textbf{side} (lactose), Lip\textbf{ase} acts on Lip\textbf{ids} (fats), Ure\textbf{ase} acts on Ure\textbf{a}.

Answer 1

The Correct Option is B

Step 1: Match each enzyme to its corresponding substrates and products.
A. \(\beta\)-galactosidase: This enzyme (lactase) hydrolyzes lactose into its monosaccharide components, corresponding to III. Galactose + glucose.
B. Lecithinase (Phospholipase): This enzyme breaks down lecithin (a phospholipid) into diglyceride (fat), phosphoric acid, and choline, corresponding to I. Choline + H$_3$PO$_4$ + fat.
C. Urease: This enzyme catalyzes the hydrolysis of urea into ammonia and carbon dioxide, corresponding to IV. CO$_2$ + NH$_3$.
D. Lipase: This enzyme breaks down fats (triglycerides) into glycerol and fatty acids, corresponding to II. Glycerol + fatty acids.
The correct matches are A-III, B-I, C-IV, and D-II.
