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

Options

  1. A(1.576 10^4 )
  2. B(1.576 10^3 )
  3. C15.76
  4. D(2.136 10^4 ).

Correct answer

A. (1.576 10^4 )

Step-by-step solution

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 = 100 78.4 0.5 =1.576 10^4 ~g of enzymes
