NFSC 475 EXAM 1 – CARBOHYDRATES
QUESTIONS WITH VERIFIED ANSWERS
{ GRADED A+}
What is basal metabolic rate (BMR)? - ✔✔energy expenditure by the
body when at rest, but not asleep, under uncontrolled conditions of
thermal neutrality, measured about 12 hours after the last meal
We can use BMR to calculate: - ✔✔energy requirements or energy
intake needed
Energy required for physical activities for sedentary, moderate, and
vigorous activity. - ✔✔Sedentary: 1.1-1.2 x BMR
Moderate: 2-5 x BMR
Vigorous: 6-8 x BMR
,Energy is generated from:
Energy sources include: - ✔✔food
carbohydrates, proteins, lipids, alcohol
How many kcal/g are in:
carbs
proteins
lipids
alcohol - ✔✔carbs - 4 kcal/g
proteins - 4 kcal/g
lipids - 9 kcal/g
alcohol - 7 kcal/g
,What is indirect calorimetry and what is it used for? - ✔✔measurement
of oxygen consumption (and CO2 production) and is used to estimate
energy requirement
RQ stands for:
What is it? - ✔✔respiratory quotient
the ratio of the production of CO2 to the consumption of O2
RQ for carbohydrates: - ✔✔RQ = 1.0
RQ for lipids: - ✔✔RQ = 0.7
RQ for proteins: - ✔✔0.8
A change in RQ indicates:
Explain. - ✔✔a shift in fuel utilization
, since lipids and carbohydrates are generally consumed together, your
RQ would range from 1-0.7. If your RQ was closer to 1, that would
mean you utilized carbs more than lipids for oxidation
Can an RQ value measured from a mouse at a given time point be 1 or
0.7? Why or why not? - ✔✔No. Glucose and lipids are burned at the
same time, so RQ would be between 1 and 0.7
What information can RQ data provide for us? - ✔✔- energy
expenditure (part of the equation)
- has physiological relevance in that it tells us the shift between glucose
and lipids as an energy source
Describe the RQ of a healthy person. - ✔✔A healthy person's RQ would
be aroun 0.85 after a meal, but after a few hours, the number would
start to decrease (meaning they're using more fat)
