Metabolism - Answer Total energy expenditure of all cata/anabolic processes (bodies ability to use fuel) Measured by either direct (calorimetry chamber) or indirect (Douglas bag/metabolic cart) calorimetry Calorimetry = measure of energy expenditure (kcals = E to heat 1kg water 1°C) Oxidation-Reduction Reaction - Answer - Are always *coupled reactions* (the energy given off by the exergonic reaction powers the endergonic reaction) - *Oxidation*: removing an electron - *Reduction*...

Measurements Chapter 1 Test Questions and Answers How do we measure energy, oxygen consumption, heart rate and multiples of resting metabolic rate? - Answer-we exercise oxygen consumption VO2 Max by absolute (not relating to body mass) and relative (respective of body mass) What's the difference between absolute and relative VO2? - Answer-Absolute VO2 is in not in relation to body mass and uses the unit Liters/Minute while Relative VO2 is in retrospect to body mass, using the unit Mililiter...

Factors that influence BMR Gender, lean body mass, body size, temperature, age, nervous system activity, caffeine, smoking, pregnancy, diet 2. Android obesity Fat being stored in the abdominal area yielding an apple shape. Common in males and linked to high blood pressure, testosterone levels, and an increased risk of diabetes and hypertension 3. Gynoid Obesity Fat stored below the waist line yielding a pair shape. More common in females and describes small waist with fat in the hips an...

Which of the following is the largest component of total energy expenditure (TEE)? A. RMR B. Thermic effect of digestion C. Physical Activity D. Metabolic Stress correct answers *A. RMR* The thermogenic effect of digestion is generally thought to contribute to no more than 10% to TEE. Activity contributes to 5% - 30% to TEE. With the exceptions of burn and sepsis, metabolic stress contributes to less than 50% TEE. However, in almost all situations, RMR constitutes 60% to 75% of TEE. Wh...

Direct calorimetry - process of measuring a person's metabolic rate via the measurement of heat production -direct measurement of metabolic rate Indirect calorimetry - direct relationship between O2 consumed and amount of heat produced -O2 consumption, CO2 production, N2 balance Oxygen deficit - -a lag due to slower activation of oxidative pathways -difference between oxygen uptake in the first few min of exercise and after an equal time period of steady state What is the steady s...

The most likely diagnosis is: A) adrenal insufficiency B) Cerebral salt wasting C) Diabetes insipidus D) syndrome if inappropriate antidiuretic hormone Sodium 128 mEg/L Potassium 4.0 mEq/L Chloride 103 mEq/L Bicarbonate 26 mEq/L BUN 10mg/dL Creatinine 0.2mg/dL Glucose 102 mg/dL Calc...

Anabolism - Uses energy to construct components of cells. Catabolism - Breaks down organic matter, for example, to harvest energy. Nutrient Density - A measure of the nutrient a food provides compared to its energy content. Trace Minerals - Needed only in tiny amounts. These minerals participate in most chemical reactions in the body. These include iron, zinc, iodine, copper, manganese. Protein Complementation - The act of consuming a variety of plant products to provide all the necessary...
