Gerontological Exam One Questions andAnswers
___ theories explain biological aging as result of complex predetermined processes -
Answers -Non stochastic theories
__ theories explain biological aging as resulting from random assaults from both the
internal and external environment - Answers -Stochastic theories
_ theory proposes that cellular division is threatened as a result of radiation or chemical
reaction in which a cross-linking agent attaches itself to a DNA strand and prevents
normal parting of the strands during mitosis cause the cross-linking agents to
accumulate. - Answers -Cross-Linking Theory [stochastic theory]
_ theory entails molecules damaging proteins, enzymes and DNA by replacing
molecules that contain useful biological information with faulty molecules that create
genetic disorder - Answers -Free Radical Theory [stochastic theory]
_ are highly unstable, reactive molecules containing an extra electrical charge that
generates from oxygen metabolism - Answers -Free radicals [stochastic theory]
_ theory entails age pigments being associated with the oxidation of unsaturated lipids.
As ti accumulates, it interferes with the diffusion and transport of essential metabolites
and information bearing molecules in cells - Answers -Lipofuscin Theory [stochastic

biological clock that predetermines the life span - Answers -Programmed theory of
aging [non stochastic theory]
_ theory proposes a genetic determination for aging. This theory holds that genetic
mutations are responsible for aging by causing organ decline as a result of self-
perpetuating cellular mutations - Answers -Error theory [non stochastic theory]
_ and _ are the primary organs of the immune system, believed to be affected by the
aging process - Answers -bone marrow and thymus

aged, irregular cells as foreign agents and developing antibodies to attack them -
Answers -Autoimmune reactions [non stochastic theory]

glands - Answers -Neuroendocrine and Neurochemical Theory [non stochastic theory]
_ suggests that repeated exposure to radiation that promotes aging and decreased life
span - Answers -Radiation theory [non stochastic theory]
_ theory suggests that good diet may minimize or eliminate some of the ill effects of the
aging procress - Answers -Nutrition theories
