Answer to Question 2

Oxygen is utilized during metabolism to change carbohydrates and fats into energy. During this process oxygen is transformed into stable forms of water and carbon dioxide. A small amount of oxygen, however, ends up in an unstable form, referred to as oxygen free radicals.
Free radicals attack and damage proteins and lipids, in particular cell membranes and DNA. This damage is thought to contribute to the development of conditions such as cardiovascular disease, cancer, emphysema, cataracts, Parkinson's disease, and premature aging. Environmental factors that seem to encourage the formation of free radicals include solar radiation, cigarette smoke, air pollution, radiation, some drugs, injury or infection, and chemicals (such as pesticides), among others.
