Free radicals,unpaired electrons,can cause aging because
A) They collect in the organs and skin forming large molecules that interfere with organ function.
B) They bond with molecules that are nearby, like DNA and proteins, causing damage to the molecule.
C) Unpaired electrons pair up together and attack DNA.
D) Free radicals seek to free other electrons so that all electrons are stripped from DNA.
E) They speed up metabolic processes causing the organs to wear out faster.

Question

Quizplus · Accepted Answer

Free radicals (unpaired electrons) are attracted to nearby molecules so that they can bond with these molecules. The addition of an electron would change the charge and shape of the molecule possibly changing the functioning of the molecule. This is especially true of DNA since it contains the directions to direct the cell's functioning. Free radicals do not play a role in the speed of metabolic processes.Bloom's
