Question

Immobilisation was first reported by

• A. J.M Nelson
• B. E.G. Griffth
• C. Sir Edward Sharpy-Shafer
• D. Both A and B

Answer 1

The correct option is D Both A and B

Immobilisation of enzymes is the process of fixing enzyme to or enclosing it in a solid support so as to use the enzyme in a continuous process. In 1916, the enzyme invertase was immobilised with the help of charcoal. Nelson and Griffin adsorbed the enzyme on charcoal and demonstrated immobilisation for the first time.

Thus, the correct answer is option D.
