Gender: the basal metabolic rate (bmr) averages 5 to 10 percent lower in women than in men this is largely because women generally hormonal levels: thyroxine (t4), the key hormone released by the thyroid glands has a significant effect upon metabolic rate. Why did the metabolic rates differ between the normal rat and the surgically altered rats what was the effect of thyroxine injections on the thyroideetomized rat's bmr how does the bmr in this ease compare with the normal rats bmr. The normal rat had the faster basal metabolic rate, because it was not missing its pituitary gland or its thyroid gland 2 why did the metabolic rates differ for the hypophysectomized rat, tsh would be missing due to the missing pituitary gland part 2 5 what was the effect of thyroxine injections on. Normal rate 2why did the metabolic rates differ because of the different organs that were removed from the two other rats that would produce certain hormones 3if an animal has been 1what was the effect of thyroxine on the normal rat's metabolic rate.
It also controls the rate of oxidation level in the thyroxine is the name of the hormone secreted by thyroid gland which does the work of metabolic activities hence the thyroxine hormone should be at the optimal level for normal health. Thyroxine aids in digestion, heart and muscle function, brain development, and bone maintenance what is thyroxine the thyroid gland is an important part of the endocrine system, secreting a number of hormones that affect everything from heart.
The thyroxine increased the normal rats metabolic rate as compared to the baseline metabolic rate there was also an increase present 1 what was the effect of propylthiouracil on the normal rat's metabolic rate how does it compare to the normal rat's baseline metabolic rate. Metabolism (pronounced: meh-tab-uh-lih-zem) is a collection of chemical reactions that takes place in the body's cells metabolism converts the fuel in the food we eat into the energy needed to power everything we do, from moving to thinking to growing.
Basal metabolic rate (bmr) is the rate of energy expenditure per unit time by endothermic animals at rest it is reported in energy units per unit time ranging from watt (joule/second) to ml o2/min or joule per hour per kg body mass j/(h g. How did the thyroxine affect the normal rat's metabolic rate 17 what is the condition that the injection of alloxan caused in the experimental rat 18 what is the effect of administering insulin to the control animal.
Metabolic rate = (ml o2/hr)/(weight in kg) = ml o2/kg/hr enter the metabolic rate in the field below and then click submit to display what was the effect of thyroxine injections on the thyroidectomized rat's bmr how does the bmr in this case compare with the. Thyroxine's effect on metabolism thyroxine is the main hormone produced by the thyroid gland and what controls the body's basal metabolic rate (bmr) by restoring normal metabolic activity from hypothyroidism or graves' disease, with the use of. Metabolic rates were raised to reach normal rates, even though still lower than baseline it has a pituitary gland so some hormones are still there what was the effect of thyroxine injections on the hypophysectomized rat's bmr how does the bmr in this case compare with the normal rat's bmr.
What was the effect of thyroxine on the metabolic rate of the normal rat it increases about 100 ml o2/kg/hr because the tsh causes the rat to grow giving a higher metabolic rate. How did the thyroxine affect the normal rat s metabolic rate the effects of the thyroxine increased the metabolic rates of each rat compared to activity 1some questions in this exercise may have more than one correct answer. Which rat had the fastest basal metabolic rate (bmr)2 why did the metabolic rates differ between the normal rat and the surgically altered rats the effect of thyroxine injections on the thyroidectomized rat's bmr.
