An injection of TSH to an otherwise normal animal will cause which of the following? 5. Thyrotropin-releasing hormone (TRH) is 6. Which of the following statements is true? 01/18/17 page 1
Experiment Results Predict Question: Predict Question 1: Make a prediction about the basal metabolic rate (BMR) of the remaining rats compared with the BMRof the normal rat you just measured. Predict Question 2: What do you think will happen after you inject thyroxine into the three rats? What do you think will happen after you inject TSH into the three rats? Propylthiouracil (PTU) is a drug that inhibits the production of thyroxine by blocking the attachment ofiodine to tyrosine residues in the follicle cells of the thyroid gland (iodinated tyrosines are linked together to form thyroxine).What do you think will happen after you inject PTU into the three rats? Stop & Think Questions: 1h. Calculate the oxygen consumption per hour for this rat using the following equation. ml O2 consumed/1 minute x 60 minutes/hour = ml O2/hour Enter the oxygen consumption per hour in the field below and then click Submit Data to display your results in the Lab Report. You answered: 420 ml O2/hr
