Judging from their basal metabolic rates (an indicator of thyroid function), categorize the rats
as hypothyroid (low thyroid levels; BMR below 1600), euthyroid ("good," or normal, thyroid
levels; BMR = 1650-1750), or hyperthyroid (high thyroid levels; BMR above 1800) after the
TSH injection.
The thyroidectomized (Tx) rat is

Which of the rats did not develop a goiter after injection with TSH? 29
Calculate the oxygen consumption per hour for this rat using the following equation.
ml O consumed/1 minute x 60 minutes/hour = ml O /hour
Enter the oxygen consumption per hour.

Now that you have calculated the oxygen consumption per hour for this rat, you can
calculate the metabolic rate per kilogram of body weight with the following equation (note
that you need to convert the weight data from grams to kilograms to use this equation).
Metabolic rate = (ml O /hr)/(weight in kg) = ml O /kg/hr
Enter the metabolic rate.

Enter the oxygen consumption per hour.
You answered: 372 ml O /hr.
Now that you have calculated the oxygen consumption per hour for this rat, you can
calculate the metabolic rate per kilogram of body weight with the following equation (note
that you need to convert the weight data from grams to kilograms to use this equation).
Metabolic rate = (ml O /hr)/(weight in kg) = ml O /kg/hr
