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.
Calculate the resting metabolic rate in units of kcal day-1
kg body-1 for a 60 kg nonathletic male and a 160 kg
nonathletic male.
Make a reasonable hypothesis as to why there is a
difference

- a Imagine that creatine phosphate, rather than ATP, is the universal energy carrier molecule in the human body. Assume that the cellular concentrations of creatine phosphate, creatine, and phosphate are 21.6 mM, 2.16x10-3 mm, and 3.80 mM, respectively. Calculate the weight of creatine phosphate that would need to be consumed each day by a typical adult human if creatine phosphate could not be recycled. (Estimate the free energy of hydrolysis of creatine phosphate under cellular conditions to determine how many moles required. Use the standard free energy AG = -43.3 kJ/mol, and take the temperature to be 37 °C.) AG= kJ/mol Weight of creatine phosphate consumed = 9arrow_forwardThis is for Animal Physiology.

If a human being consumes 12.7 kcal/min while running 8-minute miles, how long could a human run on the energy that the hummingbird consumes in its trans-Gulf flight? How many 8-minute miles would a person have to run to lose 1 pound of body fat?arrow_forward
