1. Which rat‚ A‚ B or C has no thyroid gland? Rat A (1 pts) 2. Justify your answer. (what data convinced you of your answer) (1 pts) T3 and T4 regulate the metabolism‚ so when more is available it increases the baseline metabolic rate. TSH causes the release of T3 and T4‚ so if the rat is injected with TSH‚ in theory we would suggest that the levels of T3 and T4 are also higher than the baseline metabolic rate. 3. In a further experiment‚ all 3 rats were given a drug that inhibits the production

Each rat was kept in a single housed area with controlled temperature and humidity‚ lights would turn on and off at the same time. Each rat was prepared by an 11-mm electrode within the medial forebrain bundle. Each rat began eating regular lab chow and it was slowly changed to lieber DeCarli liquid diet‚ experiments 1 and 2 had 36% of calories taken from alcohol‚ while experiment 3 had 48%taken from alcohol. Each control rat was paired with an alcohol rat based off of weight‚ and

Time/Date: 7:00 PM/Wednesday Activity 1 Metabolism and Thyroid Hormone Part 1 1 Which rat had the fastest basal metabolic rate (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 between the normal rat and the surgically altered rats? How well did the results compare with your prediction? The normal rat has the highest BMR because it has the glands required to stimulate and regulate the

LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood

study is to find out the effect of L-carnitine on the activities of electron transport chain in young and aged rats. 2. What are the main conclusions of this study? The conclusion is that carnitine may prevents free radicals mediated mitochondrial membrane damages and increases the electron flow through the electron transport chain and thereby increasing energy production in aged rats. 3. How could this study be improved? This is a very open-ended question; just do the best you can. In

The results are what I would have expected to see comparing the artic ground squirrel‚ and Brown Norway rat and Dahl rats. The graph shows that rodent with the least amount of heart damage is the artic ground squirrel that hibernates during the winter and that the Dahl Salt sensitive rat has the most levels of troponin in the blood levels meaning that
