metabolic rate 2.3 Flashcards
definition metabolic rate
the quantity of energy consumed by an organism pr unit time
how can metabolic rate be measured
oxygen consumption per unit time
carbon dioxide production per unit time
heat energy production per unit time
what instrument can be used to to measure metabolic rate
respirometer, oxygen probe, carbon dioxide probe, calorimeters
basal metabolic rate
the minimum rate of energy release needed to maintain essential body process
how to set up a control
the same experiment with the same mass of glass beads
how does a calorimeter measure metabolic rate
measuring the temperature of the water entering and leaving the calorimeter for a given period of time
