15 Questions
What percentage of daily energy is used to digest food?
10%
What is the primary purpose of knowing one's basal metabolic rate?
To maintain, lose, or gain weight
What happens when an individual consumes more calories than their basal metabolic rate?
Weight gain
How does physical activity affect basal metabolic rate?
It increases BMR
What is the primary difference between basal metabolic rate and resting metabolic rate?
BMR is the minimum energy needed, while RMR is the actual energy expenditure
What is the primary difference between Basal Metabolic Rate (BMR) and Resting Metabolic Rate (RMR)?
RMR includes calories needed for eating, sweating, and using the restroom, whereas BMR does not
What is the purpose of the Mifflin-St.Jeor equation?
To calculate the Basal Metabolic Rate in humans
What is the significance of the 'mouse-elephant curve' in calculating BMR in animals?
It describes the relationship between BMR and body mass raised to the 3/4 power
What is the difference between mass-specific metabolic rates and whole-organism metabolic rates?
Mass-specific metabolic rates are reported per unit of body mass, while whole-organism metabolic rates are reported per unit of time
What is the role of the sympathetic nervous system in measuring BMR?
It must be deactivated to measure BMR accurately

Blood type
What is an advantage of being an ectotherm?
Higher energy efficiency
