Propylthiouracil PTU is a drug that inhibits the production of thyroxine by blocking the attachment of iodine to tyrosine residues in the follicle cells of the thyroid gland iodinated tyrosines are linked together to form thyroxine.
Make a prediction about the basal metabolic rate BMR of the remaining rats compared with the BMR of the normal rat you just measured.
The prediction is a wrong depiction of how the curve works, the optical density is measured and then the glucose concentration is extrapolated using the curve?
What do you think will happen after you inject PTU into the three rats? Calculate the oxygen consumption per hour for this rat using the following equation.
To obtain an accurate spectrophotometric measurement of the glucose concentration in the sample You correctly answered: A laboratory technician withdraws a blood sample from a vein in your upper arm knowing that You correctly answered: In all cases, TSH levels were not elevated by the thyroxine injection.
To maintain plasma glucose homeostasis You correctly answered: Patient 3 appears to have diabetes based on the glucose standard curve? The thyroidectomized Tx rat is You correctly answered: Which of the following statements about metabolism is false? During the course of a pregnancy, the sugar levels rise and the body makes more insulin to get the sugar levels into the cells?
How would you treat a thyroidectomized animal so that it functions like a "normal" animal? Thyroid-stimulating hormone TSH is You correctly answered: Why did the normal rat develop a palpable goiter with the TSH injection?
What do you think will happen after you inject thyroxine into the three rats? What do you think will happen after you inject TSH into the three rats?
An injection of propylthiouracil to an otherwise normal animal will cause which of the following? It raised the BMR tobut not as high as the thyroidectomized or normal rats with thyroxine cause it is over thandose was too large Part 3: Specific to dieting, eating foods with lower sugar intake.
Did you correctly predict how you would measure the amount of plasma glucose in a patient sample using the glucose standard curve?
The healthcare provider will inform her that You correctly answered: The blood sugar is higher than normal during pregnancy due to hormonal changes, as nutrients are being supplied to the placenta. An injection of TSH to an otherwise normal animal will cause which of the following?
The glucose standard curve is a method of monitoring blood glucose over a period to identify patterns and peaks in glucose levels?
Now that you have calculated the oxygen consumption per hour for this rat, you can calculate the metabolic rate per kilogram of body weight with the following equation note that you need to convert the weight data from grams to kilograms to use this equation. The thyroidectomized rat will become hypothyroidic and develop a goiter.
Describe the diagnosis for patient 3, who was also pregnant at the time of this assay.Solved by ramonistry Exercise 4: Endocrine System Physiology: Activity 2: Plasma Glucose, Insulin, and Diabetes by ramonistry [PhysioEX Chapter 4 exercise 2] PEX ramonistry (25) 5 06/02/15 page 2.
