programmed (predictable cell death), errors (random), calorie restriction (cal reduction
increases life span) - answers-biological theories of aging
aging is the result of predictable cellular death; 3 theories: 1. immunity theory 2.
neuroendocrine control theory 3. gene theory - answers-programmed theories of aging
aging is a programmed accumulation of decline in function of immune system resulting from
oxidative stress - answers-immunity theory of aging
aging is a programmed decline in functioning of nervous, endocrine, immune systems; cells lose
abililty to reproduce - answers-neuroendocrine theory of aging
longevity associated with genetic trait; "juvenescent" = youthful vigor/mature adult well-being;
"senescent" = functional decline/structural deterioration - answers-gene theory of aging
aging is a result of accumulation of random errors in the synthesis of cellular DNA and RNA; 3
theories: 1. oxidative 2. cross-linkage 3. wear and tear - answers-errors theories of aging
free radical theory; errors are a result of random damage from free radicals - answers-oxidative
stress theory
1
