Question
This use of energy to fuel normal body functions is called your aMetabolism bBasal Metabolic Rate cFat Burner dExercise Rate
Solution
The use of energy to fuel normal body functions is called your bBasal Metabolic Rate. This is the amount of energy your body needs to perform basic functions, such as breathing and circulation, while at rest.

A person's body temperature is controlled by the following.convective and radiative heat transfer to the surroundingssweatingrespiration by breathing surrounding air and exhaling it at approximately body temperatureblood circulation near the surface of the skinmetabolic rateMetabolic rate determines the rate of conversion of chemical to thermal energy within a person's body. The metabolic rate depends on the person's activity level. A unit commonly used to express the metabolic rate for an average person under sedentary conditions (per unit surface area) is called met; 1 met is equal to 58.2 W/m2. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)(a)How many square feet are equal to 1 square meter? ft2How many Btu/h are equal to 1 watt?

When you jog, most of the food energy you burn above your basalmetabolic rate (BMR) ends up as internal energy that would raise your bodytemperature if it were not eliminated. The evaporation of perspiration is theprimary mechanism for eliminating this energy. Determine the amount of wateryou lose to evaporation when running for 45 minutes at a rate that uses 450kcal/h above your BMR. (That amount is often considered to be the “maximumfat-burning” energy output.) The metabolism of 1 gram of fat generatesapproximately 9.0 kcal of energy and produces approximately 1 gram of water.(The hydrogen atoms in the fat molecule are transferred to oxygen to formwater.) What fraction of your need for water will be provided by fatmetabolism? (The latent heat of vaporization of water at room temperature is 2.5× 106 J/kg)
Os componentes do gasto energético compreendem a taxa metabólica basal (TMB), o fator de atividade e o efeito térmico dos alimentos (ETA). A taxa metabólica basal representa a quantidade mínima de energia necessária para manter as funções vitais do organismo em repouso, como a respiração, a circulação sanguínea e a manutenção da temperatura corporal. O fator de atividade considera o gasto energético adicional relacionado às atividades físicas realizadas ao longo do dia, variando de acordo com o nível de atividade física de cada indivíduo (Medonça et al., 2017).

Revista Brasileira de Obesidade, Nutrição e Emagrecimento, São Paulo, v. 11, n. 65, p. 476-484, set./out. 2017. Considerando as informações apresentadas, avalie as asserções a seguir e a relação proposta entre elas: I. O efeito térmico dos alimentos (ETA) corresponde, aproximadamente, de 5 a 15% do gasto diário de energia. PORQUE II. O gasto energético da atividade física corresponde de 15 a 30% do gasto energético total, variando entre os indivíduos, pois engloba atividades físicas do cotidiano e o exercício físico.A respeito dessas asserções, assinale a opção correta: AlternativasAlternativa 1:As asserções I e II são proposições verdadeiras, e a II é uma justificativa correta da I.Alternativa 2:As asserções I e II são proposições verdadeiras, mas a II não é uma justificativa correta da I.Alternativa 3:A asserção I é uma proposição verdadeira, e a II é uma proposição falsa.Alternativa 4:A asserção I é uma proposição falsa, e a II é uma proposição verdadeira.Alternativa 5:As asserções I e II são proposições falsas.
