The normal rat will go hyperthyroidic and develop a goiter. Predict Question 4: Propylthiouracil (PTU) is a drug that inhibits the production of thyroxine by blocking the zipper of iodine to tyrosine residues in the follicle cells of the thyroid gland (iodinated tyrosines are linked together to form thyroxine). What practise yous think will happen after yous inject PTU into the three rats? Your reply : d. The normal rat volition become hypothyroidic and develop a goiter. Cease & Call up Questions:

1h. Calculate the oxygen consumption per hr for this rat using the following equation. ml O2 consumed/ane minute x hour/hour = ml O2/hour
Enter the oxygen consumption per hour in the field beneath and then click Submit to display your results in the grid. You answered: 420 ml O2/hr
1i. Now that yous have calculated the oxygen consumption per hour for this rat, y'all can summate the metabolic rate per kilogram of trunk weight with the following equation (notation that you need to convert the weight data from grams to kilograms to use this equation).

Metabolic rate = (ml O2/hr)/(weight in kg) = ml O2/kg/hr
Enter the metabolic charge per unit in the field below and then click Submit to brandish your results in the grid. You answered: 1673.306773 ml O2/kg/hr 2h. Summate the oxygen consumption per hour for this rat using the following equation. ml O2 consumed/1 minute 10 sixty minutes/hour = ml O2/hour Enter the oxygen cnsumption per hour in the field below and then click Submit to brandish your results in the grid.

3i. Now that you take calculated the oxygen consumption per 60 minutes for this rat, you tin can calculate the metabolic rate per kilogram of body weight with the following equation (note that yous need to catechumen the weight data from grams to kilograms to utilise this equation).

Metabolic rate = (ml O2/60 minutes)/(weight in kg) = ml O2/kg/hr
Enter the metabolic rate in the field beneath and then click Submit to display your results in the grid. You answered: 1549.180328 ml O2/kg/hr
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 hyperthryoid (high thyroid levels; BMR above 1800).
