Question

Quizplus · Accepted Answer

Oxidative stress occurs when there is an imbalance between free radicals (oxidizing molecules) and antioxidants in the body. If cells are exposed to more free radicals than antioxidants, it can cause damage to cell structure and even DNA, leading to various diseases and aging processes. It is not a brain disease, immune response, galactose disorder, or stroke.
