Which individual would you predict to have a higher basal metabolic rate, a man who is 6 feet tall weighing 200 pounds or a man who is 5 feet, 9 inches tall weighing 160 pounds? Explain your answer.
Which of the following conditions is not applicable to measuring basal metabolic rate? a. reclining b. the time immediately after a meal c. room temperature d. resting
Basal Metabolic Rate (BMR) is the amount of energy your body uses to function at rest in a day. This includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning, and the body temperature stabilized. Approximately 70 percent of an individual’s energy expenditure goes into basal metabolism. The other 30 percent goes into digestion and absorption of nutrients (10%) and physical movement (about 20%).
Calculate your basal metabolic rate in Calories using the appropriate equation here:
Females: BMR = 655 + (9.6 × wt(kg)) + (1.8 × ht(cm)) – (4.7 × age(yrs))
Males: BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs))
Calculate how many Calories you burn overall in a day.

- Which of the following definitions best describes an individuals Basal Metabolic Rate? The amount of energy used while eating. O The amount of calories required to support an active lifestyle. O The ratio of total cholesterol / HDL. ( The number of calories to keep a body functioning at rest.arrow_forwardWhen you jog, most of the food energy you burn above your basal metabolic rate (BMR) ends up as internal energy that would raise your body temperature if it were not eliminated. The evaporation of perspiration is the primary mechanism for eliminating this energy. Determine the amount of water you lose to evaporation when running for 32 minutes at a rate that uses 400 kcal/h above your BMR. (That amount is often considered to be the "maximum fat-burning" energy output. The latent heat of vaporization of water at room temperature is 2.5 106 J/kg.)The metabolism of 1 gram of fat generates approximately 8.65 kcal of energy and produces approximately 1 gram of water. (The hydrogen atoms in the fat molecule are transferred to oxygen to form water.) What fraction of your need for water will be provided by fat metabolism?arrow_forwardA student weighing 700 N took a weight management course with a Basal Metabolic Rate (BMR) of 1500 kcal, which is 20% of their total daily fat intake. If a student consumed 40.0 g of fat in a day, how many minutes would the student perform sitting exercises at the rate of 1 time per second? (Up-down counts as 1 time) to burn excess fat received if each time the center of gravity shifts to a distance of H = 50.0 cm, as shown in the figure, muscle efficiency is 25% and fat 1.0 g provides 9.0 energy. kcal (1 kcal = 4184 J) CG CGarrow_forward

Age D. Time of Day E. Hormonesarrow_forwardDiazepam is used as a skeletal muscle relaxant and as a sedative administered before surgery, as well as a treatment for anxiety. For children above the age of 6 months who suffer from anxiety disorders, diazepam is administered at a reduced dosage. Suppose a child with a body surface area (BSA) of 0.8 m2 is to receive a dose of diazepam divided into three administrations. Using the BSA rule and assuming that an adult dose of diazepam is 12 mg, what are the daily dose and the dose per administration? mgarrow_forward
- Define basal metabolic rate and discuss factors that can decrease or increase it.arrow_forwardThe thermoneutral zone is the range of body temperatures over which an animal can maintain a constant basal metabolic rate. Which of the following patterns about thermoregulation is true? A. Below the lower critical threshold, animals must decrease their metabolic rate in order to maintain body temperature B. Animals living in the arctic have higher critical temperatures than do animals in the tropics C. When outside temperatures are below the lower critical temperature for an animal, animals in the arctic increase their metabolic rate faster than do animals in the tropics D. All of the above E. None of the abovearrow_forwardAssume that you want to lose 20 lb of body fat in 60 days. Your present dietary intake is 3000 Cal/ day. What should your caloric intake be, in Cal/day, to achieve this goal, assuming no change in exercise habits?arrow_forward
- What is thermoregulation and why is it necessary for the human body to function properly? List two physiological responses the human body takes to when its core temperature gets too high. Briefly explain how each works to reduce core temperature. Explain why one of these responses will not work if the air temperature is extremely high. Explain why one of these responses will not work if the relative humidity is extremely high.arrow_forwardGenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect normal levels of dissolved glucose (70. to 105 mg/dL), using a blood sample that is as small as 5.0 mL. Calculate the minimum mass in milligrams of glucose that the new system must be able to detect. Be sure your answer has the correct number of significant digits.arrow_forwardThe acceptable daily intake (ADI) of the additive E100 = 20 mg per kg of bodyweight per day. The maximum usable dose for E100 in "water-based flavoured drinks, energy-reduced or no added sugar" is 400mg/litre of drink. What volume of a fizzy drink containing the maximum usable dose of E100 would a 80 kg adult need to drink to equal the ADI of E100? (show all calculations)arrow_forward
