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

A

`1.576 xx 10^4`

B

`1.576 xx 10^3`

C

`15.76`

D

`2.136 xx 10^4`

Text Solution

Verified by Experts

The correct Answer is:
A
The enzyme must contain at least one atom of Se.
`:. `0.5 g of Se is present in 100 g of enzyme
` therefore ` 78.4 g of Se will be present in =`( 100 xx 78.4 )/( 0.5)`
`= 1.576 xx 10^4 ` g of enymes
