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!).

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.


What is the effect of TSH on normal metabolic rate?

Thyroid-stimulating hormone (TSH) plays a crucial role in regulating the metabolic rate by stimulating the thyroid gland to produce thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3). These hormones increase the basal metabolic rate (BMR) by enhancing cellular metabolism, promoting energy expenditure, and influencing the metabolism of carbohydrates, fats, and proteins. A normal level of TSH ensures that thyroid hormone production is balanced, thereby maintaining an appropriate metabolic rate essential for overall health and energy levels. An imbalance can lead to conditions such as hyperthyroidism or hypothyroidism, affecting metabolic processes.


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.


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.


Which abiotic factor has the biggest effect in the metabolic rate of animals?

tempreture


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 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 pituitary hormone necessary to govern metabolism?

Thyroid-stimulating hormone (TSH) is a pituitary hormone that controls metabolism by stimulating the thyroid gland to produce thyroid hormones, which regulate the body's metabolic rate.


Which cell has the higher metabolic rate?

the liver has a higher metabolic rate


What is TRH's role in the endocrine system?

Thyrotropin-releasing hormone (TRH) is produced by the hypothalamus and stimulates the release of thyroid-stimulating hormone (TSH) from the pituitary gland. TSH then acts on the thyroid gland to stimulate the production and release of thyroid hormones, which regulate metabolism and energy balance in the body.
