Hypophysectomized rats do not have the thyroxine with which to regulate metabolic rate properly. Thyroxine replacement can allow for the normalization of the metabolic rate (as it does in humans with hypothyroidism!).
TSH or Thyroid Specific Hormone is created by the thyroid. A rat without a thyroid gland will not produce TSH. A mammal without a thyroid and without thyroxin or synthoid injections would have a greatly reduced metabolism, and would be lethargic.
TSH stimulates thyroxine release from the thyroid gland, and thyroxine stimulates catabolic metabolism. In short, TSH increases the metabolic rate.
TSH would take BMR of hypohysectomized rat to normal
these answers will not help you with ezzedines paper lol
minimal effect. It make it go down slightly
I don't know and WHY do you need to know that?????
(who does know that?) :P
If the rats are hypophysectomized, there will be no thyroid hormone available for TSH to act on. Therefore, there will be no effect of TSH administration to the rats under these conditions.
it decreased it BMR.
None. TSH is a signal fo rthe thyroid to make and release more thyroid hormone. If the thyroid is removed TSH wil have no effect.
The effect of administering thyroxin on each of the rats was the baseline metabolic rate increased in each rat. Thyroxin was the most important hormone in maintaining metabolism and body heat.
tempreture
Propylthiouracil is a drug given to patients with goiter to decrease or slow down basal metabolic rate.
Water flea is poikilothermic, which means that its body temperature and metabolic rate are afffected by the temperature in the environment. The change in metabolic is then reflected in the heartbeat rate
it stimulates the thyroid to produce the thyroid hormone which regulates metabolic rate
1. Resting metabolic rate (RMR) or basal metabolic rate (BMR), which equals sleeping metabolic rate (SMR) and arousal. 2. The thermogenic effect of food. 3. Exercise, or daily physical activity and spontaneous physical activity (SPA).

the liver has a higher metabolic rate
The rate of Metabolism, or metabolic rate.
Elevating your heart rate increases your basal metabolic rate in an individual.
