- Figure 37.11 Pancreatic tumors may cause excess secretion of glucagon. 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.Give two examples of feedback control of hormone activity.Discuss and trace the pathway of the production of insulin, starting from the stimulation by glucose.
- Which of the following rows correctly identifies the endocrine disorder, the level of the hormones involved, and a physiological consequence? Select one: a. Endocrine Disorder Hormone Physiological Consequence Addison's Too little cortisol and aldosterone Rapid weight gain b. Endocrine Disorder Hormone Physiological Consequence Cushing's Too much cortisol and aldosterone Water retention c. Endocrine Disorder Hormone Physiological Consequence Cushing's Too little cortisol and aldosterone Sodium imbalance d. Endocrine Disorder Hormone Physiological Consequence Addison's Too much cortisol and aldosterone Increased blood pressureBriefly explain how glucagon and insulin keep balance of blood glucose levels? Please briefly explain at your own words.Compare rapid-, short-, intermediate-, and long-acting insulins with regard to their onset of action, peak effects, and duration of action
- Compare and contrast the functions and modes of action ofthe following pairs of hormones: insulin and glucagon; activevitamin D and parathyroid hormone; adrenocorticotropichormone (ACTH) and cortisol.Match each hormone with its general effects on metabolism: promotes glycogenesis (storing glucose) insulin promotes lipogenesis (storing fats) glucagon and cortisol secretion increases when blood insulin glucose increases promotes glycogenolysis (breaking down glycogen) glucagon and cortisol promotes gluconeogenesis (making glucose) insulin > > > > >Cortisol and epinephrine act synergistically to decrease blood glucose. true or false
- Describe the most important hormones released during acute and chronic stress. Describe the interactions between insulin and glucagon release in the regulation of glucose metabolism. How is this related to stress conditions?While insulin levels are primarily regulated by blood glucose, other factors are also able to influence insulin levels. Briefly describe the major positive and negative factors.Describe the function of the insulin molecule in the body.
