front 1 Beta oxidation is the initial phase of fatty acid oxidation, and it occurs in the cytoplasm. | back 1 False |
front 2 The increased use of noncarbohydrate molecules for energy to conserve glucose is called glucose sparing. | back 2 True |
front 3 Except for lactose and some glycogen, the carbohydrates we ingest are mainly from animals. | back 3 False |
front 4 The term essential nutrient refers to the chemicals that can be interconverted in the liver so that the body can maintain life and good health. | back 4 False |
front 5 The most abundant dietary lipids in the diets of most Americans are triglycerides. | back 5 True |
front 6 There are no complete proteins. All animal products should be eaten with plant material to make a complete protein. | back 6 False |
front 7 The body is considered to be in nitrogen balance when the amount of nitrogen ingested in lipids equals the amount excreted in urine. | back 7 False |
front 8 The amount of protein needed by each person is determined by the age, size, and metabolic rate of the person. | back 8 True |
front 9 Vitamins are inorganic compounds that are essential for growth and good health. | back 9 False |
front 10 Cellular respiration is an anabolic process. | back 10 False |
front 11 Glycolysis is a series of six chemical steps, most of which take place in the mitochondria. | back 11 False |
front 12 Glycogenesis begins when ATP levels are high, and glucose entering cells is phosphorylated to glucose-6-phosphate and converted to its isomer, glucose-1-phosphate. | back 12 True |
front 13 All athletes require diets high in protein and calories in order to perform and to maintain their muscle mass | back 13 False |
front 14 In order for amino acids to be oxidized for energy, the amine group (NH2) must be removed. | back 14 True |
front 15 Including the ATP from glycolysis, the cell gains 34 ATP molecules from aerobic metabolism of one glucose molecule. | back 15 False |
front 16 The body requires adequate supplies of only three minerals (calcium, sodium, chloride) and trace amounts of all others. | back 16 False |
front 17 Processes that break down complex molecules into simpler ones are anabolic. | back 17 False |
front 18 For use as fuel, all food carbohydrates are eventually transformed to glucose. | back 18 True |
front 19 Triglycerides and cholesterol do not circulate freely in the bloodstream. | back 19 True |
front 20 Normal body temperature range is 98.6-100°F, regardless of external temperature. | back 20 False |
front 21 A deficit of potassium can cause rickets. | back 21 False |
front 22 It would not be healthy to eliminate all fats from your diet because they serve a useful purpose in maintaining the body. | back 22 True |
front 23 The body's thermoregulatory centers are located in the thalamus. | back 23 False |
front 24 Carbohydrate and fat pools are oxidized directly to produce cellular energy, but amino acid pools must first beconverted to a carbohydrate intermediate before being sent through cellular respiration pathways. | back 24 True |
front 25 High levels of HDLs are considered good. | back 25 True |
front 26 Diets high in cholesterol and saturated fats tend to produce high HDL concentrations. | back 26 False |
front 27 Ghrelin, produced by the stomach, is a powerful appetite stimulant. | back 27 True |
front 28 Peptides called NPY and AgRP are powerful appetite enhancers. | back 28 True |
front 29 The primary function of carbohydrates is energy production within cells. | back 29 True |
