BIOD 121 (portage): Module 3 Problem Set Questions and Answers Rated A+ 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. 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 have le...

Direct Calorimetry - ️️measure's the body's heat production to estimate energy expenditure Indirect Calorimetry - ️️calculated energy expenditure from the ration of CO2 produced to O2 consumed. Oxygen Consumption (VO2 max) - ️️the rate of O2 and CO2 exchanged in the lungs = rate of use and released by the body tissues Two ways to measure Oxygen Consumption - ️️-Indirect Calorimetry Method -VO2 max VO2 max Best Method - ️️single best measurement of cardiorespira...

Energy Balance - ANS Occurs when energy consumed equals energy expenditure. -Energy in vs. Energy out -Energy in= BMR + TEF + PA Energy Units of Measure - ANS Kilojoules (kJ) -Unit of Work Kilocalories (kcal) -Unit of heat -1,000 calories= 1 kcal Sources of Stored Energy in the Body - ANS Glycogen -In liver and muscle -1,400 kcal Glucose or Lipids -In body fluids -100 kcal Triglyceride -In adipose tissue -115,000 kcal Protein -In muscle -...

NUTR 121 Final Exam with Questions and Answers Describe energy balance and the uses of energy by the body. ANSWER The state in which energy intake, in the form of food and beverages, matches the energy expended, primarily through basal metabolism and physical activity. Negative energy balance is when energy output suprasses energy intake resulting in weight loss. Positive energy is opposite. Energy needs met by food intake (protein, carbs, fat, alcohol). The body uses energy for 3 general pu...
