WGU C458 Objective Assessment Review (Latest 2024/ 2025 Update) Health, Fitness, and Wellness | Qs & As| Grade A| 100% Correct (Verified Answers) Q: slow the aging process. Reduce cellular damage by binding with free radicals produced during oxidation reactions Answer: Antioxidants Q: the energy-yielding reactions in which either an oxygen atom adds an electron to or a hydrogen atom removes an electron from a substrate (a group of atoms or molecule)—the net result is a substrate that has had a partial or complete loss of a negatively charge particle, an electron. Two partially charged atoms or groups of atoms, one positively charged and the other negatively charged, now exist Answer: Oxidation reactions Q: any atom or group of atoms that has an unpaired electron. Because electrons typically function in pairs, these are very prone to binding to other substrates in an effort to regain this paired status. When this happens in the human body, there is potential for a great deal of damage. Answer: Free radical (Oxidant) Q: produce 4 calories of energy per gram. Found in foods as monosaccharides, disaccharides, and polysaccharides. Sources include fruits, vegetables, pasta, and rice which consist of simple sugars and starches Answer: Carbohydrates Q: produce 4 calories of energy per gram. Sources include meats and milk. Composed of 8 essential(provided by the diet) and 12 nonessential(synthesized by the body) amino acids. Perform many functions including building cells and tissues, forming blood and enzymes, and fighting infection. means primary, and no organism can live, and almost no biological process can take place, without it Answer: Protein Q: produce 9 calories of energy per gram. Organic compounds that do not readily dissolve in water; based on their solubility, they are classified into triglycerides (more commonly known as fats), phospholipids, and sterols Answer: Lipids Q: proteins that are lacking one or more of the essential amino acids Answer: Incomplete protein Q: the polysaccharide form in which glucose is stored in the liver Answer: Glycogen Q: simple sugar. The only source of energy that brain cells use to function Answer: Glucose Q: Solid at room temperature. Group of chemical compounds that contain fatty acids, often in very long strands. Most concentrated source of energy in the diet. Provides much of the stored energy of the body. Insulate body organs against changes in environmental temperature. Protect the organs and underlying tissues by acting as a shock absorber. Answer: Triglycerides (Fats) Q: essential component of body structure. Second only to oxygen in importance to body functioning. Acts as a solvent for minerals and other physiologically important compounds. In the body, it transports nutrients to and waste products from the cells and helps regulate body temperature. Comes from fluids and solids in the diet and also is produced by the metabolic processing of energy nutrients within the tissues Answer: Water Q: liquid at room temperature. Answer: Oils Q: organic compounds required by every part of the body to maintain health and prevent disease. Classified as either fat-soluble or water-soluble. Do not become part of the body. Only small amounts are needed, but must be provided by the diet because the body is not able to synthesize them in the required quantities for proper nourishment and body function. Foster growth, promote the ability to produce healthy offspring, maintain health, aid in the normal function of the digestive tract and appetite, and help maintain immune system functions. Answer: Vitamins Q: found in the fatty parts of food and body tissues. Stored in the body until needed, so it is not necessary to consume them every day. Transported by lipids through the body; A, D, E, and K Answer: Fat-soluble vitamins Q: important in promoting growth and health of body tissues as well as enhancing the function of the immune system. Enhances vision by helping the retina function properly, permitting us to distinguish between light and shade and to see various colors distinctly. A form of this is used by dermatologists to treat acne and other skin disorders. Overdoses may result in yellowish, dry, scaly skin and dry, irritated eyes Answer: Vitamin A
