LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood
