To protect themselves, What compound can plants produce? A. salicylic B. acetic acid C. water D. carbon dioxide If a psychoactive substance is used or abused over a long period of time, a person may be unable _____. An _____ is a substance that protects vulnerable molecules from free radicals. Asked By adminstaff @ 22/09/2019 04:38 PMStart studying Chapt. 8. Learn vocabulary, terms, and more with flashcards, games, and other study tools.An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reactions can produce free radicals, which start chain reactions that damage cells.2. Free radicals. Free radicals are molecular species with unpaired electrons in their atomic orbital capable of independent existence. As such, these radicals are highly reactive and can either extract an electron from molecules or donate an electron to other molecules thus acting as a reductant or an oxidant.Antioxidants keep free radicals in check. Antioxidants are molecules in cells that prevent free radicals from taking electrons and causing damage. Antioxidants are able to give an electron to a free radical without becoming destabilized themselves, thus stopping the free radical chain reaction.

Importance of Antioxidants to Counter Free Radicals Free radicals are molecules or atoms that are unstable and are produced courtesy of the normal process of metabolism and from external sources like exposure to industrial chemicals, air pollutants, etc. It is a fact that we are exposed to free radicals all the time because they are everywhere.what substance protects vulnerable molecules from free radicals . an antioxidant. what are fat-soluble vitamins. A, d, e, and K. water-soluble . B and C . body can store large amounts of what B vitamin. B-12. about ____% of an average healthy young man's body weight is water. 60.the Free Radical theory of aging. According to the free radical theory of aging, free radicals break down cells over time. Numerous studies support this relatively new theory. There have been studies on rats showing significant increases in free radicals as the rats aged, which match up with age-related declines in the health of humans.. This research suggests that free radicals produced inEat foods rich in antioxidants, chemicals that inhibit the oxidation of molecules by neutralizing free radicals, thereby stopping them from causing cellular damage. Antioxidants are found in a...

Vitamin C helps counteract UV free radical stress and pollution. Resveratrol protects skin from UVB damage. Niacinamide can be used for inflammation, redness, brown spots or pigmentation. Other...Cellular metabolism self-adapts to protect against free radicals Date: a lot of energy is generated from a few sugar molecules and oxygen. cells' tolerance to oxidised substances; howeverAn antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reaction can produce free radicals, which start chain reactions that damage cells.Diets contain naturally occurring antioxidant compounds that can stabilize highly reactive, potentially harmful molecules called free radicals. Free radicals are generated during normal cellular metabolism and result from the metabolism of certain drugs or xenobiotics. Exposure to UV light, cigarett …Think you know how bad cigarette smoke is for your health? Swallow this fact: Every puff of a cigarette contains about 4,700 different chemicals and 100 trillion free radical molecules. These reactive substances damage lung tissue by chemically reacting with DNA, cell membranes and other molecules in the lung.
