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

Options

A. (a)`1.576xx10^(4)`
B. (b)`1.576xx10^(3)`
C. (c )`15.76`
D. (d)`2.136xx10^(4)`

Answer

c

Explanation

The enzyme must contain at least one atom of Se.
`:. 0.5 g` of Se is present in `100 g` of enzyme
`:. 78.4 g` of Se will be present in `(100xx78.4)/0.5`
`=1.576xx10^(4) g` of enzymes
