QUESTIONS AND 100% CORRECT DETAILED ANSWERS
Bio energetics
Ans: study of biological conversion
-no amount of physical energy/work is possible without the body's ability to convert
energy in food into a usable form (ATP)
Quiz efficiency of conversion
Ans: ATP/total energy converted
Quiz krebs cycle occurs where
Ans: mitochondria
Quiz electron transport chain occurs where
Ans: mitochondria
Quiz glycolysis occurs where
Ans: cytoplasm
Quiz creatine phosphate occurs where
Ans: cytoplasm
Quiz creatine phosphate limited by
Ans: substrate (CP: inorganic phosphate)
Quiz glycolytic pathway limited by
, Ans: limited by pH (H+ levels)
Quiz metabolism
Ans: rate at which the body breaks down things into usable energy; all energy
exchanging reactions in the body
Quiz conceptual definition of metabolism
Ans: sum total of all energy converting/exchanging reactions in body
Quiz operational definition of metabolism
Ans: the rate of heat production by the body in kcal/min
Quiz direct calorimetry
Ans: directly measure metabolism by measuring heat released by the body
Quiz limitations to direct calorimetry
Ans: -not reliable during exercise
-core temp and body temp is not the same; body temp is not uniform
-ergometers release heat themselves
Quiz indirect calorimetry
Ans: measures O2 consumption/CO2 production with is directly proportional to heat
release
Quiz indirect calorimetry limitations
Ans: -during high intensity anaerobic contributions are ignored
- assumes that cellular level = whole body gas exchange
- hyperventilation
- non metabolic CO2 given off by buffers
Quiz Respiratory Quotient
Ans: ratio of CO2 produced/O2 consumed at the CELLULAR LEVEL- dependent on
fuel metabolized
*always between .71 - 1.0
Quiz Respiratory Exchange Ratio
Ans: same ratio as RQ but allows WHOLE BODY measure
*can be greater than 1 because of hyperventilation
Quiz non-protein RQ
