This unit in the Discussion you will explore the aging process. Although the exact causes of aging are not yet known, researchers have made promising advances identifying cellular changes as we age. One theory follows damage in the cell as it ages. The accumulation of damage ultimately causes either malfunction or death of the cell. The cause of this damage may be by free radicals, which are chemical compounds that can come from the environment and also normal cellular functions. Free radicals contain unpaired electrons. These highly reactive molecules scour the cell in an effort to neutralize their electric charge. This oxidative process causes damage to various parts of the cell including the DNA. For this unit’s Discussion you will need to respond to the following: Be sure to answer all Discussion topics in an original, well-thought-out manner. Main posts should consist of approximately 200-250 words.
