AP PSYCHOLOGY

Detailed explanation-1: -[5] The most important oxygen-containing free radicals in many disease states are hydroxyl radical, superoxide anion radical, hydrogen peroxide, oxygen singlet, hypochlorite, nitric oxide radical, and peroxynitrite radical.

Detailed explanation-2: -Exercise can lead to an increase in free radical production due to increased activation of aerobic bioenergetic pathways during endurance exercise, substrate depletion and exercise-induced hyperthermia.

Detailed explanation-3: -Cooked and Processed Meats Preservatives used in processed meats–including sausages, bacon, ham, pepperoni, hotdogs, salami, corned beef and many deli meats–may also create free radicals. The American Institute for Cancer Research recommends avoiding processed meats and marinating meats you intend to grill.

Detailed explanation-4: -A molecule with one or more unpaired electron in its outer shell is called a free radical (1-5). Free radicals are formed from molecules via the breakage of a chemical bond such that each fragment keeps one electron, by cleavage of a radical to give another radical and, also via redox reactions (1, 2).
