What does the end of the metabolic process yield? - correct answer ATP, CO2, H2O,
and heat
What are the 2 ways energy can be measured in? (units) - correct answer kilocalories
(kcal) <-- United States
and
kilojoules (kJ)
A kcal is the amount of energy (heat) required to raise the temperature of ___ kg of
water by 1° C.
1 kilocalorie is ____ calories. - correct answer 1
1000
The International unit of measurement for energy? - correct answer Joule (J)
A kJ is equal to the amount of energy expended when 1 kg of a substance is moved 1 m
by a force of 1 ______. - correct answer newton (N)
kcal --> kJ conversion - correct answer kJ = multiplying the number of kcal by 4.184
e.g: 150 kcal × 4.184 = 627.6 kJ.
,What are the 3 Macronutrients? - correct answer Carbohydrates
Fats
Proteins
Non-nutrient substances, such as _______ (i.e., ethanol), also provide energy. - correct
answer Alcohol
What is the fuel density of each Macronutrient? (including alcohol) - correct answer
Carbohydrates = 4 kcal/gram
Proteins = 4 kcal/gram
Fats = 9 kcal/gram
Alcohol = 7 kcal/gram
Bomb Calorimeter - correct answer A closed, two-chamber system used to burn food
and measure the heat (energy) given off by the food sample.
Most often used in research to determine exact values.
All cells in the body require cellular energy in the form of... - correct answer ATP
(NOTE: Energy is required for both voluntary and involuntary actions)
Voluntary Actions
, Examples? - correct answer An anticipated action for the purpose of achieving a goal
e.g: Conscious movement, physical activity, activities of daily living
Involuntary Actions
Examples? - correct answer An action that occurs without conscious choice
e.g: Respiration, blood circulation, growth, tissue repair, temperature regulation, basal
metabolic rate, thermic effect of food (increase in energy expenditure as a result of
functions of digestion, absorption, transport, and storage of food)
TEE
TEE equals the sum of three energy needs: - correct answer Total Energy Expenditure
1) Basal metabolism (involuntary)
2) Thermic effect of food (involuntary)
3) Physical activity (voluntary)
BEE
How much of total energy expenditure (TEE) does BEE account for? - correct answer
Basal Metabolic Rate, aka basal energy expenditure.
The amount of energy (kcal) needed by the body to maintain life at complete rest.
