Explanation:
Detailed explanation-1: -Antioxidants neutralize free radicals by giving up some of their own electrons. In making this sacrifice, they act as a natural “off” switch for the free radicals. This helps break a chain reaction that can affect other molecules in the cell and other cells in the body.
Detailed explanation-2: -Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. Antioxidants are also known as “free radical scavengers.” The body makes some of the antioxidants that it uses to neutralize free radicals.
Detailed explanation-3: -Selenium acts as antioxidant by directly donating an electron to stabilize free radicals.
