- 1Describe the free radical theory of aging- free radicals produced by normal respiration in cells evade antioxidant defenses causing damage to macromolecules (lipids, proteins, DNA)
- this leads to cellular damage, which leads to organ dysfunction, then disease and ultimately death - 2Describe Pearl's rate of living hypothesis- states there is an inverse relationship between lifespan and metabolic rate (so species that live longer have a lower metabolic rate and vice versa)
- speculate there is some finite metabolite, so if metabolism is fast this metabolite is rapidly depleted leading to cell and organ dysfunction and ultimately death - 3—
