    Consider the following statements about enzyme to prevent ageing
    1. Researchers of Institute of Himalayan Bio-resource Technology (IHBT) discovered an enzyme named Super Oxide Dismutase (SOD).
    2. SOD can be used in cosmetic, food and pharmaceutical compositions. Which of the statement(s) given above is/are correct?

    A)  Only 1 

    B)  Only 2

    C)  Both 1 and 2    

    D)  neither 1 nor 2

    Correct Answer: C

    Solution :

    [c] Super Oxide Dismutases (SOD) are enzymes that catalyze the dismulation of superoxide into oxygen and hydrogen peroxide. Thus, they are important anti-oxidant defense in nearly all cells exposed to oxygen. SOD is extracted from a high altiude plant Potentilla found in Himalayan region. This enzyme is believed to slow down the effects of ageing. Trials are being done on lower animals.
