NUTR 331 MIDTERM EXAM QUESTIONS AND
ANSWERS SURE A+
✔✔if nitrogen intake is equal to nitrogen output, the subject is: - ✔✔consuming enough
protein to replace body losses
✔✔which protein source can be used as a reference standard in measuring the quality
of other proteins? - ✔✔egg whites
✔✔describe a peptide bond and outline which digestive tract sites break it down - ✔✔a
peptide bond is the chemical bond connecting an acid group on one amino acid with the
amine group of another. The peptide bond is broken down by enzymes in the stomach
and small intestine.
✔✔T/F on a nutritious diet, children and pregnant women have a positive nitrogen
balance - ✔✔T
✔✔T/F Incomplete proteins will not be absorbed because of lack of one or more EAA -
✔✔F
✔✔T/F athletes and bodybuilders need protein supplements because they require more
protein than can be supplied by ordinary foods - ✔✔F
✔✔T/F most adult Canadians need to increase their protein intakes - ✔✔F
✔✔when are ketones produced? - ✔✔when there is insufficient glycerol to combine with
fatty acids to produce triglycerides
✔✔the physiological fuel value of a food is: - ✔✔the amount of energy available to the
body
, ✔✔Basal metabolic rate (BMR) - ✔✔is measured under a controlled set of conditions
✔✔what activity is not part of basal metabolism? - ✔✔digestion
✔✔average body weight in women - ✔✔20-30%
✔✔the most accurate method of assessing the degree of body fatness is by: - ✔✔skin
fold measurement
✔✔which sex has a typically higher percentage in body fat - ✔✔higher in women than in
men
✔✔which health hazard is not associated with serious underweight? -
✔✔hyperlipidemia
✔✔which effect is not a result of a low-carb diet? - ✔✔deficiency of ketone bodies

storage of fat? - ✔✔fat, carbs, and proteins
✔✔what is the body's most likely response to surplus dietary fat? - ✔✔excess fat will
almost all be stored as body fat
✔✔after the first day or so of fasting, which component is most depleted in the body? -
✔✔glycogen
✔✔what type of diet is related to ketosis? - ✔✔low-carb
✔✔weight loss in first few days on low-carb diet is most likely due to: - ✔✔water
✔✔what is the approximate percentage of Canadian adults with BMI over 25.0 -
✔✔60%
✔✔what is the BMI of a woman who is 165cm and 57kg? - ✔✔21
✔✔what is primary advantage of using BMI to classify risk for disease? - ✔✔BMI is
inexpensive and easy to determine
