WGU C795 STUDY GUIDE WITH SOLVED
QUESTIONS AND ANSWERS
◉ Lipids.
Answer: 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
◉ Incomplete protein.
Answer: proteins that are lacking one or more of the essential amino
acids
◉ Glycogen.
Answer: the polysaccharide form in which glucose is stored in the
liver
◉ Glucose.
Answer: simple sugar. The only source of energy that brain cells use
to function
◉ Triglycerides (Fats).
,Answer: 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.
◉ Water.
Answer: 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
◉ Oils.
Answer: liquid at room temperature.
◉ Vitamins.
Answer: 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.
◉ Fat-soluble vitamins.
Answer: 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
◉ Vitamin A.
Answer: 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
◉ Vitamin D.
Answer: essential for calcium absorption and thus is needed to
prevent and cure rickets(deficiency disease in which bones fail to
harden)
◉ Vitamin E.
, Answer: an activator in certain enzyme reactions, and it protects
vitamins A and C from being used up too quickly
◉ Vitamin K.
Answer: essential for the synthesis of prothrombin, a substance
needed for normal blood coagulation.
◉ Water-soluble vitamins.
Answer: associated with the watery parts of food and body tissues.
Not stored by the body. Excess amounts are usually excreted in the
urine and, therefore, should be provided in the diet on a regular
basis. Includes the B vitamins and vitamin C (ascorbic acid)
◉ B vitamins.
Answer: essential to daily human nutrition. Known as the B-complex
group, they help body systems combat stress and maintain energy
reserves. The B-complex group consists of vitamin B1 (thiamin),
vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B6
(pyridoxine), vitamin B12 (cobalamin), folic acid, and biotin.
◉ Vitamin B1 (thiamin).
Answer: necessary for carbohydrate metabolism. Aids in the release
of energy from food
