Cumulative Damage from Reactive ________ is Thought to Be a Major

Question

Cumulative damage from reactive ________ is thought to be a major factor in aging.
A) nitrogen
B) double bonds
C) isotopes
D) free radicals
E) helium

Accepted Answer

Free radicals are highly reactive molecules that can cause damage to cells, including DNA and other important cellular structures. Over time, this cumulative damage is thought to contribute to aging and age-related diseases. Nitrogen (A), double bonds (B), isotopes (C), and helium (E) do not play significant roles in reactive damage and aging.
