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.
Which of the following is TRUE regarding liver metabolism? Select three of the following:
The liver (hepatocytes) has hundreds of functions, such as producing glucose, ketones,
fatty acids, cholesterol, proteins, and bile for the rest of the body.
Hepatocytes have the GLUT2 antiporter, which allows for secondary active transport of
glucose into the cells.
Hepatocytes have glucokinase that continually makes glucose 6-phosphate, and it has a
lower Km than other hexokinases so it continuously metabolizes glucose when
concentrations are low.
Glucose 6-phosphate is the "transfer station" in the liver since it can be made my multiple
pathways and have multiple fates.
The liver converts amino acids to citric acid cycle intermediates or pyruvate for
gluconeogenesis.
The liver oxidizes fatty acids into glucose, which can be sent to other cells and used for
energy or converted into phospholipids and triacylglycerol.

For a person who weighs W pounds and who is H inches tall, the body-mass index B is given by W 8 = 703-2 A body-mass index is considered "normal" if it satisfies 18.5 ≤ B s 24.9, while a person with body-mass index B 2 30 is considered obese.
