Textbook Question
Chapter 50, Problem 3CQ
Core Concept: Systems Organ systems often exert dual control over variables such as blood pressure, respiration, and growth. How do the opposing actions of insulin and glucagon maintain glucose homeostasis? When are these hormones released into the blood? What might happen to a nonfasting mammal that was injected with a high dose of glucagon?

Exercise
Exercise places demands on the body. Cells require extra energy and water is lost through sweating. The breathing rate and heart rate increases during exercise to deliver more glucose and oxygen to cells which are converted to ATP through cellular respiration. Identify three hormones that are involved in re-establishing homeostasis after an intense workout and explain why they are involved.
Why is it that hormones act only on their target organs? Name hormones that have
most body organs as their target organs. Hypothyroidism and hyperthyroidism may
lead to marked increase/ decrease, respectively, in body weight. Why is that so?
Discuss the similarities and differences between thyroid hormone and steroid
hormones. Illustrate the secretion of insulin hormone
Chronic stress or GC exposure can cause insulin resistance. The influence of GC on insulin is complex, but leads to hyperinsulinemia (high circulating insulin levels) and insulin resistance. Insulin resistance is typically caused by a decreased number of insulin receptors on the cell surface. Speculate on a mechanism resulting in a decreased number of insulin receptors.

The body typically attempts to compensate by producing greater amounts of TSH. Which of the following symptoms would you expect goiter to cause? a. Hypothyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. b. Hyperthyroidism, resulting in weight loss, profuse sweating and increased heart rate. C.

Type I diabetes results from the failure of the pancreas to produce insulin. Which of the following statement about these two conditions is true? A pancreatic tumor and type I diabetes will have the opposite effects on blood sugar levels. A pancreatic tumor and type I diabetes will both cause hyperglycemia. A pancreatic tumor and type I diabetes will both cause hypoglycemia. Both pancreatic tumors and type I diabetes result in the inability of cells to take up glucose.arrow_forward

Some examples include insulin, glucagon, adrenaline, and cortisol.Select the FOUR numbers below that correctly show the pathway for insulin. Insulin is secreted when blood sugar levels are high. Insulin is secreted when blood sugar levels are low. Insulin is released from the beta cells of the pancreas. Insulin is released from the alpha cells of the pancreas. Insulin makes cells more permeable to glucose. Insulin makes cells less permeable to glucose. Glycogen is taken up and converted to glucose. Glucose is taken up and converted to glycogen.arrow_forward
