BIOD 121 (PORTAGE): MODULE 3 EXAM
QUESTIONS AND ANSWERS GRADED A+
2025/2026
Energy balance - ANS a state when one's energy intake is equivalent to the amount of energy
expended
Energy in equals energy out (calories consumed is burned through basic body functions +
exercise - ANS energy balance
positive energy balance - ANS occurs if more calories (energy) are consumed than expended
examples of periods in life when you need to be in a positive energy balance state: -
ANS pregnancy, childhood, and adolescence in growth spurts
1 pound in a week is equivalent to : - ANS 500 extra calories a day
Hyperplasia - ANS an increase in the number of fat cells often occurring during periods of
growth, such as adolescence or pregnancy
Hypertrophy - ANS an increase in the size of fat cells, most often seen in periods of low
growth and maintenance, such as throughout adulthood

, Negative energy balance - ANS occurs if fewer calories are consumed than calories expended
Examples of negative energy balance situations: - ANS during illness or trauma, major burn
injury, intentional act such as dieting to meet a weight loss goal
Our sole source of energy intake is from: - ANS food and beverages
Energy can be expended naturally via _____________ , _____________, and
_________________ - ANS basal metabolism, the thermic effect of food, and thermogenesis
Energy can be expended intentionally through _______________ - ANS physical activity (aka
exercise)
Two major components of energy expenditure are: - ANS basal metabolic rate and physical
activity
Basal metabolic rate (BMR) - ANS the number of calories used by the body while in a fasting
state and accounts for approximately 60-70% of energy expenditure
BMR varies by person based on factors such as: - ANS gender, lean body mass, body size,
temperature, age, nervous system activities, levels of caffeine intake, and tobacco use
BMR males: - ANS 1 kcal/kg/hour
BMR females: - ANS 0.9 kcal/kg/hour
As we age BMR declines by ______________% per decade so we must adjust eating habits to
prevent weight gain. - ANS 1-2 %
