NEET Questions Solved


Percentage of Se in peroxidase anhydrase enzyme is 0.5% by weight (at. weight = 78.4), then minimum molecular weight of peroxidase anhydrase enzyme is

(a) 1.568 x 10

(b) 15.68

(c) 2.168 x 10

(d) 1.568 x 10

(d) Suppose the molecular weight of enzyme =  x

0.5% by weight means in 100g of enzyme weight of Se=0.5g

In xg of enzyme weight of Se = .5100×x

Hence, 78.4 = 0.5 × x100

x = 15680 = 1.568x104
