Homeostasis Correct Answer The automatic tendency to maintain a relatively constant internal environment.
Metabolism Correct Answer The total of all the chemical and physical processes by which the body builds and maintains itself (anabolism) and by which it breaks down its substances for the production of energy (catabolism).
Glucose Correct Answer Principal circulating sugar in the blood and the major energy source of the body.
ketone bodies Correct Answer Bodies produced as intermediate products of fat metabolism.
lactic acid Correct Answer A by-product of glucose and glycogen metabolism in anaerobic muscle energetics.
Amino acid Correct Answer The building blocks of protein. There are 24 amino acids, which form countless number of different proteins.
fatty acids Correct Answer Any of a large group of monobasic acids, especially those found in animal and vegetable fats and oils.
Anabolism Correct Answer The building up in the body of complex chemical compounds from simpler compounds (e.g., proteins from amino acids).
Catabolism Correct Answer The breaking down in the body of complex chemical compounds into simpler ones (e.g., proteins to amino acids).
Metabolic set point Correct Answer The base rate of metabolism that the body seeks to maintain; resulting in basal metabolic rate.
basal metabolic rate (BMR) Correct Answer The minimum energy required to maintain the body's life function at rest; usually expressed in calories per hour per square meter of the body surface.
thermic effect Correct Answer The heat liberated from a particular food; it is a measure of its energy content and its tendency to be burned as heat. This process of heat liberation is also commonly referred to as "thermogenesis"
Calorie Correct Answer A unit of heat; specifically, it is the amount of energy required to raise the temperature of 1 gram of water 1 degree Celsius at 1 atmosphere.
kilocalorie (kcal) Correct Answer A unit of measurement that equals 1,000 calories, or 1 Calorie. Used in metabolic studies, it is the amount of heat required to raise the temperature of 1 kilogram of water 1 degree Celsius at a pressure of 1 atmosphere. The term is used in nutrition to express the fuel (energy) value of food.
Respiratory Quotient (RQ) Correct Answer A method of determining the "fuel mix" being used, giving us a way to measure the relative amounts of fats, carbohydrates, and proteins being burned for energy.
Oxidation Correct Answer The chemical act of combining with oxygen or of removing hydrogen. [Show Less]
