For exercise 4,

Activity 1: Determining Baseline Metabolic Rates (pp. 45–47)

I only have # 12

Activity 2: Determining the Effect of Thyroxine on Metabolic Rate (p. 47)

On the normal rat, the metabolic rate after thyroxine injection is faster than the baseline metabolic rate. The action of thyroxine is to increase the metabolic rate of all cells. On the thyroidectomized rat, the metabolic rate after thyroxine injection is faster than the baseline metabolic rate. The injected thyroxine compensated for the thyroxine lost when the thyroid was removed. On the hypophysectomized rat, the metabolic rate after thyroxine injection is faster than the baseline metabolic rate. The injected thyroxine compensated for the thyroxine lost when the pituitary gland was removed. The pituitary gland did not produce TSH, therefore the thyroid gland did not produce thyroxine.

Activity 3: Determining the Effect of TSH on Metabolic Rate (pp. 47–48)

7. On the normal rat, the metabolic rate after TSH injection is faster than the baseline metabolic rate. The TSH increased production of thyroxine. On the thyroidectomized rat, the metabolic rate after TSH injection is the same as the baseline metabolic rate. Since there is no thyroid gland in the thyroidectomized rat, the injected TSH had nothing to act upon. There was no organ to receive the pituitary TSH and produce thyroxine, On the hypophysectomized rat, the metabolic rate after TSH injection is faster than the baseline metabolic rate. The injected TSH compensated for the TSH lost when the pituitary gland was removed, and spurs production of thyroxine.

Do you have the answer to Exercise 4 Activity 1?

Activity 1: Determining Baseline Metabolic Rates (pp. 45–47)

16. The normal rat’s metabolic rate is faster than the metabolic rates of the thyroidectomized and hypophysectomized rats.
The thyroidectomized rat lacks a thyroid, thus produced no thyroxine. The hypophysectomized rat lacks a pituitary gland, thus produced no thyroid stimulating hormone to stimulate thyroxine production. Because the normal rat produced thyroxine normally, its metabolic rate was faster than the other rats.

There is also a large chart (which I will not release, since you do not have >25 Posts).

PhysioEx is a payed-for manual by the forum. Although we don't charge for our service, what we do ask in return is for our users to contribute to the forum; you have less than <10 posts/replies. To those with less than <25 quality posts, we only give samples of the answers found in the manual. Hope you understand.
