A peroxidase enzyme isolated from red blood cells was found to contain 0.28% selenium. The minimum molecular mass of the enzyme is (at. Mass of selenium = 78.96 u).

Options

A. `3.67xx10^(3)`
B. `2.7xx10^(4)`
C. `2.90xx10^(7)`
D. `2.9xx10^(4)`

Answer

B

Explanation

Selenium content = 0.29% `=2.9xx10^(-3)`
Minimum mol. Mass `=("At. Mass of Se")/("Selenium content")`
`=(78.96u)/(2.9xx10^(-3))=2.7xx10^(4)u`
