Type 1 diabetes is caused by destruction of beta cells in the pancreas that produce insulin. Which of the following best explains why a person with this disease needs medication? a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway. b. Medication is needed to allow alternate signaling transduction pathways to control glucose levels. c. Medication is needed to open channels to allow signaling molecules to enter pancreatic cells. d. Medication is needed to serve as second messengers to regulate glucose uptake by cells.

Step 1
Insulin is a hormone that regulates glucose uptake by cells. Since the beta cells are destroyed, the person with type 1 diabetes cannot produce enough insulin to regulate glucose levels in the body. Now let's analyze the options: a. Medication is needed to act Show more…

5) Blood sugar is regulated by two pancreatic hormones—insulin and glucagon. When blood sugar rises, insulin is released; it binds to receptors and, through signal transduction, results in an increase in glucose uptake by cells, which effectively lowers blood glucose levels. When blood sugar decreases, glucagon is released, binds to cell receptors, and causes glucose to be released into circulation, thereby increasing blood glucose levels. Diabetes mellitus is a disorder that results from excessively high levels of blood glucose. Type II diabetics have normal to elevated levels of insulin. What, then, might be causing their elevated blood glucose levels? A) inadequate insulin production B) defective receptors C) defective second messenger D) overproduction of glucagon

Type 1 Diabetes is an autoimmune disorder that significantly impacts homeostasis. The irony of diabetes is that there is plenty of glucose in the bloodstream, but the cells can't utilize it. Explain why this occurs. Explain how cells can use fats in order to generate energy through glycolysis. Explain how the process of beta-oxidation creates ketones. What organ relies on ketones for energy? Explain why those with Type 1 Diabetes have elevated levels of both glucose and ketones. The sympathetic system has five identified receptor classes: Beta 1, Beta 2, Beta 3, Alpha 1, Alpha 2. The parasympathetic system primarily uses muscarinic receptors. a. Where in the body are beta 1 receptors primarily found, and what effect do they have on this tissue? b. If you want to develop a compound to cause bronchodilation, which receptor would you target, and would you develop an agonist or antagonist? c. The sympathetic and parasympathetic systems are said to be antagonistic. Explain what this means, and give one example of how antagonistic control works in one body system. d. What are TWO receptors that you would target to increase blood pressure, and would you utilize agonists or antagonists?
Which of the following is a likely cause of diabetes? a. Overproduction of insulin by $\beta$ cells of the pancreas $b .$ Loss of $\alpha$ cells of the pancreas $c .$ Loss of insulin receptors $d .$ Overproduction of glucagon e. Loss of receptors for somatostatin
