  1. What are the four forms of energy our bodies use?
    • Chemical
    • Electrical
    • Mechanical
    • Thermal
  2. What are the three sources of stored energy and in what order are they utilized during periods of fasting?
    • 1st-Glycogen
    • 2nd-Adipose fat tissue
    • 3rd-Muscle tissue
  3. What three components make up the total energy requirment?
    • BMR
    • TEF
    • Physical activity
  4. BMR=
    Basal Metabolic Rate
  5. RMR=
    Resting Metabolic Rate
  6. SDA=
    Specific dynamic action or TEF
  7. TEF
    Thermal effect of food
  8. TEE
    Total energy expenditure
  9. TDEE=
    Total daily energy expenditure
  10. What does BMR measure?
    Measure of the energy required to maintain the body at rest (not including digestion)
  11. What does resting metabolic rate measure?
    BMR + Digestion
  12. What does thermic effect of food (TEF) measure?
    The energy needed to absorb and metabolize a macronutrient (i.e. digestion)
  13. What are some factors that increase BMR?
    • Growth
    • lean body mass
    • youth
    • Stress
    • Change in environmental temperature 
  14. What are some factors that decrease BMR?
    • Malnutrition
    • Fasting/starving
    • Thyroxin
    • Smoking
    • Caffeine
    • lack of sleep
  15. what does the respiratory coefficient (RQ) represent?
    estimation of the BMR based on carbon dioxide production
  16. RQ=?
    RQ = CO2 eliminated/O2 consumed
  17. Macronutrient RQ's
    CHO (carbs) = ?
    Fat = ?
    Protein = ?
    Average mix = ?
    RQ = 1 = 
    • CHO (carbs) = 1.0
    • Fat = 0.7
    • Protein = 0.8
    • Average mix = 0.8-0.85
    • RQ = 1 = complete oxidation
  18. What does adaptive thermogenesis do?
    Increased total energy expanded in periods of stress
  19. What are three examples of adaptive thermogenesis?
    • Extreme cold
    • Overfeeding
    • Trauma
  20. What are the two types of natural simple sugars?
    • Monosaccharides
    • Disaccharides
  21. What three natural sugars are monosaccharides?
    • Glucose
    • Fructose
    • Galactose
  22. What are the three Disaccharides?
    • Sucrose
    • Lactose
    • Maltose
  23. What are complex carbohydrates?
    • Starches 
    • Glycogen
    • (Polyglucose molecules)
  24. What types of fatty acids have no double bonds?
    Saturated
  25. Unsaturated fatty acids consist of ?
    • Monounsaturated (double bonds)
    • Polyunsaturated (Multiple double bonds) 
    •                       -omega 3 & 6
  26. What are the characteristics of metabolic pathways?
    • Irreversible
    • Every pathway has a committed step
    • Metabolic pathways are regulated
    • some metabolic pathways are compartmentalized
