Q

The Theory of Aging and Oxidative Stress

A

*It refers to the functional loss that occurs due to the irreversible and progressive increase of molecular oxidative damage.
*Oxidative damage may be inadequately repaired or eliminated.

Q

Factors Playing a Role in The Theory of Aging and Oxidative Stress

A
  • Increase in the amount of oxidative stress with age
  • Increase in the amount of free radical formation
  • Decrease in antioxidant defenses
  • Reduction in removal or repair of damaged molecules

Q

Somatic Mutation Theory

A

*It refers to the accumulation of mutation in the genetic material of somatic cells that occurs during cell division when the DNA nucleotides that carry their hereditary codes are mismatched or lost. results in a decrease in cellular function

Q

genetic theory

A

It is the theory of aging that tries to explain the functioning of the aging process with the hereditary characteristics of the living thing.

Q

antioxidants

A

*defense systems that detoxify free radicals in cells.
*It protects the organism against oxidative changes.
A high antioxidant defense system can slow down physiological damage and aging.
