Direct calorimetry - Study guides, Class notes & Summaries

CSEP-CEP Study Guide Theory Exam Questions & Answers 2024/2025 Metabolism - ANSWERSTotal 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 - ANSWERS- Are always *coupled reactions* (the energy given off by the exergonic reaction powers the endergon...

BIOD 121 LEARNING PORTAGE NUTRITION MODULE 3 PROBLEM SET which person is at a greater risk for health issues related to being overweight or obese? Janet has a BMI of 28 and a waist to hip ratio of 0.95. Fred has a BMI of 28.9 and a waist to hip ratio of 0.78. - CORRECT ANSWER-Janet. Both have a BMI that indicates being overweight, but Janet has a more at-risk waist to hip ratio as her value is greater than 0.8. (Women should have a waist to hip ration less than 0.8 and males should ha...

BIOD 121 (Portage): Module 3 Latest Version Graded A+ Energy balance a state when one's energy intake is equivalent to the amount of energy expended Energy in equals energy out (calories consumed is burned through basic body functions + exercise energy balance positive energy balance occurs if more calories (energy) are consumed than expended examples of periods in life when you need to be in a positive energy balance state: pregnancy, childhood, and adolescence in growth spur...

Carbohydrate is stored in the body as___ while fat is stored as ____ a. glycogen; triglycerides b. ATP; adipocytes c. glucose; glycerol d. glycogen; ATP correct answers a. glycogen; triglycerides Protons from NADH enter the ETC at gate__ while protons from FADH enter at gate ___. This is important because ______________ a. 2;1 it influences how many ATP are ultimately made b. 2;2 it enables the protons to get from cytosol to mitochondria c. 1;2 it influences how many ATP are ultimately...

Energy sources - Carbs and protein= 4 cal/gram; fat= 9 cal/gram; the brain uses glucose for energy, uses ketone bodies during starvation Tissue storage of glucose - Muscles and liver= store glycogen; adipose tissue= fat; cellular mass= protein stores Gluconeogenesis= conversion of non-carb sources into glucose by glycerol and amino acids Homeostasis - Keeps the internal environment/temp of the body at a state of equilibrium Cellular oxidation - Enzymes= proteins, organic catalysts tha...

What are the 7 fundamental characteristics that separate animals and protist's? (Lec 1) Ans 1. They are eukaryotes 2. Animals are multicellular 3. Animals are diploid dominant 4. Animals have cells that lack cell walls 5. Animals are chemoautotrophic 6. Animals at one point in their life cycle were motile and react to external stimuli due to muscle and/or nervous tissue. 7. Development via Blastula and Gastrula stages What is metabolism? (Lec 2) Ans Metabolism is the sum of all chemi...

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...

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...
