Step 1

Enzymes are proteinaceous substances present in cells. They serve as catalysts and accelerate chemical reactions in cells. They are involved in most of all biochemical reactions occur in the body. In the chemical reaction, enzymes are used to produce products from the substrates. They catalyze all metabolic reactions in cells.

Step 2

Free radicals are often generated from various metabolic processes in the body. An increased amount of free radicals can affect several cellular mechanisms by inducing oxidative damage to deoxyribonucleic acid (DNA), protein, or lipid. The most frequently produced free radicals are superoxide radicals.

Step 3

Superoxide dismutase (SOD) is an enzyme that protects cells from various reactive oxygen species. The superoxide dismutase plays an important role in the antioxidant defense mechanism by protecting cells from superoxide radicals. In oxygen metabolism, the superoxide is generated as a by-product and induces damage to cells.  This enzyme converts the superoxide anion (O...
