Question

3. A peroxidase enzyme is isolated from human red
blood cells was found to contain 0.29% Selenium
(at. wt = 79) by weight. What is the minimum
molecular weight of the enzyme ?​

Answer 1

Answer:

Explanation:

Minimum molecular mass = mass of an atom × no of atoms/ % of element × 100%

Minimum molecular mass = 79×1/ 0.29 × 100%

Minimum molecular mass = 7900÷0.29

Minimum molecular mass = 27,241.37

Minimum molecular mass = 2.7241 × 10^-4
