AIPMT PRELIMS 2001 Chemistry Enzymes MCQ Question
Type: MCQ-numerical-Medium-Class 11
Percentage of Se in peroxidase anhydrous enzyme is 0.5% by weight (at. wt = 78.4) then minimum molecular weight of peroxidase anhydrous enzymes is : -
A
568 × 10⁴
B
568 × 10³
C
15.68
D
136 × 10⁴
Correct Answer
Option A
Detailed Explanation
If Se is 0.5% by weight, then 0.5 g of Se is present in 100 g of enzyme. Using the atomic weight of Se, calculate the molecular weight: (78.4/0.5) × 100 = 1.568 × 10⁴.
