Unit 2 Practical Scientific Procedures and Techniques Assignment B - Undertake calorimetry to study cooling curves I was awarded a DISTINCTION for this assignment.

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*...

How many calories is a pound of fat? Correct Answer-Equivalent to 3500 calories What are the 3 components of total energy expenditure? Correct Answer-70% Resting metabolic rate (RMR) , 10% thermic effect of food (TEF), & 20% Physical activity make this Name at least 4 factors that affect RMR (resting metabolic rate) Correct Answer-1) Body size 2) Body composition 3) Age 4) Hormones (book says gender, but they're getting at hormones); e.g., burn more cals when you are on your period ...

Does the use of a nutrition risk indicator identify patients who will most likely benefit from nutrition therapy? CORRECT ANSWER yes, NUTRIC score and risk screening should be used. High nutrition risk identifies those patients most likely to benefit from early EN therapy. What additional tools, components, or surrogate markers provide useful information when performing nutrition assessments in critically ill adult patients? CORRECT ANSWER Nutrition assessment should include an evaluation of ...

Student Exploration: Calorimetry Lab Vocabulary: calorie, calorimeter, joule, specific heat capacity Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. The Latin word calor means “heat,” and meter comes from the Greek word meaning “to measure.” What do you think a calorimeter does? ______________a device used to measure the heat transferred from a substance to another substance_________________ 2. Where have you heard the word calorie before? What do you think a calori...

Define Calorimetry Correct Answer-Determining the changes in energy of a system by measuring the heat exchanged with the surroundings Know how to calculate amount of energy released using E=mc(delta)T Correct Answer-E=energy, m=mass, c=specific heat, (delta T)=change in temp What is meant by a small calorie "c" and a food calorie "C"? Correct Answer-c=1 calorie=4.184 J, C=1000 little calories=4184 J When walking, an average person burns .453 C/(mile*pounds). How many C does a 150-po...

Know your significant figure rules Correct Answer-ALL zeroes between non-zero numbers are ALWAYS significant. ALL zeroes which are SIMULTANEOUSLY to the right of the decimal point AND at the end of the number are ALWAYS significant. ALL zeroes which are to the left of a written decimal point and are in a number >= 10 are ALWAYS significant. define calorimetry Correct Answer-the act of measuring heat required or evolved during a chemical process know how to calculate the amount of ener...
