Hormones and Regulation of Metabolism
Questions to Ponder…… Hormones and Regulation of Metabolism
1. Patrick was diagnosed with Diabetes mellitus on his 8th birthday. His 65-year old aunt was just diagnosed with Diabetes also. Patrick is having a hard time understanding why he needs injections, while his aunt controls her blood sugar with diet and oral medication. Why is his aunt’s treatment different from his?
Patrick’s diagnosis is different than his aunt’s because he has Diabetes Mellitus type 1. This is when the body no longer produces insulin. The body no longer produces insulin because the beta cells of the pancreas were destroyed. Whereas with Diabetes Mellitus type 2 the body produces insulin but the receptors don’t recognize the insulin. This means the insulin can’t bind.
2. Melatonin has been suggested as a possible aid for sleeping problems due to jet lag and rotating work schedules (shift work). Explain how melatonin may affect sleeping.
Your body naturally produces melatonin. When you take extra melatonin your body will have a hard time adjusting back to normal. This may cause change a person’s sleeping pattern.
3. Brian is in a 50-mile bike-a-thon on a hot summer day. He’s breathing dust at the back of the pack (he’s in last place), he’s sweating profusely, and now he’s lost his water bottle. Brian is not having a good time. How will his hormones respond to decreased intake of water and the stress of the situation? (Hint: try to name more than 1 hormone and use your notes)
Brian’s body would start to produce more ADH. ADH would allow him to retain the water his body does have. His body would also start to produce more epinephrine due to the stress he is under.
4. Would someone with Addison’s disease have normal, low, or high levels of ACTH in the blood?
JFK had Addison’s disease. A person with Addison’s disease would have low levels of ACTH.
5. Which disease is the result of antibodies mimicking the action of TSH?
6. Why is the hormone glucagon, sometimes
