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. `1.568 xx 10^(4)`
B. `1.568 xx 10^(3)`
C. `15.68`
D. `2.136 xx 10^(4)`

Answer

A

Explanation

In peroxidase anlydrous enzyme 0.55 Se is present means , 0.5 gm. Se is present in 100 gm of enzyme
In a molecule of enzyme one Se atom must be present hence 78.4 gm Se will be present in `100/0.5xx78.4=1.568xx10^4`
