Ch 20 Metabolism
Metabolism, Nutrition, and Body Temp
| Question | Answer |
|---|---|
| What are the two types of activities that make up metabolism? | Catabolism, the breakdown of compounds into smaller simpler components, and anabolism, the building of simple compounds into needed substances. |
| What name is given to the series of cellular reactions that releases energy from nutrients? | Cellular respiration |
| What is the organic end product of glycolysis? | Pyruvic acid |
| What element is required for aerobic cellular respiration but not for glycolysis? | Oxygen |
| What is removed from amino acids before they are metabolized for energy? | Nitrogen |
| What is the term for how rapidly a food raises the blood glucose level? | Glycemic index |
| What is meant when an amino acid or a fatty acid is described as essential? | It cannot be made metabolically and must be taken in as part of diet. |
| What is the difference between saturated and unsaturated fats? | Saturated fats have no double-bonded carbons and have the maximum number of hydrogen atoms possible. Unsaturated fats have one or more double bonded carbons and less than the maximum number of hydrogen atoms possible. |
| What is the difference between vitamins and minerals? | Minerals are chemical elements, and vitamins are complex organic substances. |
| How much pure alcohol can the average person metabolize per hour? | 1/2 oz |
| What condition results from lack of any specific nutrient in the diet? | Malnutrition |
| What does the abbreviation BMI stand for? | body max index |

| What does an antipyretic drug do? | reduces fever |
| What change occurs in cutaneous blood vessels under cold conditions? Under hot conditions? | cold- constrict, hot- dilate |
| What is the term for excessively low body temp? | hypothermia |
| The amt of energy needed to maintain life functions while at rest is | basal metabolism |
| Reserves of glucose are stored in liver and muscle as | glycogen |
| The area of the brain most important for temperature regulation is the | hypothalamus |
| The term febrile describes a person who has a | fever |
| The removal of nitrogen groups from amino acids in metabolism is called | deamination |
| Major energy source for the body. | glucose |
| Chemical element required for normal body function. | mineral |
| Complex organic substance required for normal body function. | vitamin |
| A byproduct of fatty acid metabolism. | ketone bodies |
| A simple fat. | triglyceride |
| Which of the following is NOT an example of catabolism? | glycogen formation |
| Which of the following would have the lowest glycemic effect? | starch |
| Which organ catabolizes alcohol? | liver |
| What is the term for a gradual decrease in a fever? | lysis |
| GLYCO | SUGAR, SWEET |
| LYSIS | SEPARATING, DISSOLVING |
| PYRO | FIRE, FEVER |
| THERMO | HEAT |
