Direct calorimetry works because approximately ____% of the energy the body uses, eventually leaves as heat.Multiple choice question.60408020

Calorimetry:

A disadvantage of direct calorimetry is thatGroup of answer choicesit is less accurate than indirect calorimetryit cannot be used for measurements of resting energy expenditurethe heat generated by exercise equipment must be taken into accountenergy expenditure during prolonged exercise cannot be measured

Which of the following parameters is measured using a calorimeter?  Group of answer choicesThe heat energy evolved in a combustion reaction.The entropy of a combustion reaction. The amount of oxygen consumed in a combustion reaction.The density of a solution.

What is the term used to estimate energy expenditure by measuring the amount of body heat released by a person?Multiple choice question.Estimated heat releaseIndirect calorimetryDirect calorimetryEstimated energy requirement

Which one of the following statements is TRUE? Question 18Select one:a.In the metabolism laboratory class, we used open-circuit, direct calorimetry methods to measure basal metabolic rate.b.The 2nd Law of Thermodynamics states that the Total Internal Energy contained in a glucose molecule is free energy that is available to drive metabolic processes.c.Resting metabolic rate is calculated under strict standardised clinical conditions and determines the amount of energy expended to sustain vital functions when awaked.Direct calorimetry estimates metabolic rate from the amount of O2 consumed and CO2 produced by a living organism.e.The respiratory quotient indicates the type of macronutrient an organism is predominantly metabolising at the cellular/tissue level.
