metabolic rate Flashcards
1
Q
define metabolic rate
A
the sum of all energy an animal uses - measures in J cal kcal
2
Q
what does a respirometer measure
A
the oxygen uptake over a period of time
- oxygen taken of the organism causes a decrease in volume of the enclosed gas (liquid rises)
3
Q
why is a water bath used
A
to ensure there are no temperature fluctuations
- temp changes cause change in vol of air effecting rate of respiration
4
Q
what does a calorimeter measure
A
carbon dioxide and heat production
- temp changes –> measurement of heat energy released
5
Q
what is basal metabolic rate
A
keeping the organism alive in order to measure energy for processes such as keeping heart beating, breathing, maintaining body temp
