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!).

∙ 13y agoTSH 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.
Wiki User
∙ 15y agoTSH stimulates thyroxine release from the thyroid gland, and thyroxine stimulates catabolic metabolism. In short, TSH increases the metabolic rate.

(who does know that?) :P

∙ 13y agoIf 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.

What is the effect of TSH on the thyriodectomized rats metabolic rate?
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.
Why did a normal rat's metabolic rate decrease when injected with thyroxine?
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.
Which abiotic factor has the biggest effect in the metabolic rate of animals?
tempreture
What is the effects of tsh injection on normal rat?
Propylthiouracil is a drug given to patients with goiter to decrease or slow down basal metabolic rate.
How does temperature effect a water fleas heart 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
What is TRH's role in the endocrine system?
it stimulates the thyroid to produce the thyroid hormone which regulates metabolic rate
What are three components of energy expenditure?
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).
What are the components of total energy expenditure?
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).
Which cell has the higher metabolic rate?
the liver has a higher metabolic rate
The rate at which the chemical reactions in the body cells take place is known as the __________ rate.?
The rate of Metabolism, or metabolic rate.
What increases the basal metabolic rate in an individual?
Elevating your heart rate increases your basal metabolic rate in an individual.
