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...

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 (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...

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...

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...

UNH Nutr 400 Final Exam Study Guide Leads to stable body weight - Energy balance The process of an adipocyte filling with lipids and increasing its cell size - Hypertrophic growth _______ is the basic physiological drive to consume food while ______ is the psychological desire for food - Hunger, appetite 3 main components to a healthy weight loss program - Healthy diet, physical activity, reasonable goals Anorexia is characterized by _____ - Irrational fear of weight gain Pu...

positive energy balance more calories consumed than expended 2. negative energy balance fewer calories consumed than expended 3. hyperplasia increase in number of cells (e.g., fat cells in childhood, pregnancy) 4. hypertrophy increase in cell size (low growth and maintenance, such as throughout adulthood) 5. basal metabolic rate the number of calories used by the body while in a fasting state accounts for approximately 60-70% of energy expenditure males 1kcal/kg/hr, femals 0.9kcal...

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*...
