1. Common BiologicalTheories of Aging
Answer
- Free Radical Theory
- Cross Linkage Theory
- Biological Clock Theory
- Wear and Tear Theory
2. The Free Radical Theory
Answer
states that "free radicals" are formed from incomplete molecule formation or overexposure to
harmful substances. This leads to the destruction of healthy DNA, cells, and connective tissues
reducing function and viability. As an individual ages, "free radicals" destroy healthy cells and
tissues more readily, this predisposes the individual to various diseases.
3. The Cross-Linking Theory
Answer
Also referred to as the glycosylation theory of aging, states that accumulation of cross-linked
proteins damages cells and tissues,slowing down bodily processes resulting in aging.
4. Free Radical
Answer
Molecules that are harmful and unstable that are produced by process of metabolism or
exposure to harmful substances
Free radical spread can be limited by
-smoking cessation
-limiting sun exposure
-limiting UV light exposure
-Diet management
