Textbook Question
Chapter 38, Problem 5FIB
The pancreas releases the hormone _________ when blood glucose levels become too high; it causes many cells of the body to take up glucose. When the pancreas produces too little of this hormone, or body cells cannot respond to it, a disorder called _______ results. ______ is released when blood glucose levels become too low; it causes the liver to break down the starch-like storage molecule _______ and release glucose into the blood.

When blood sugar is ________ the islets of Langerhans release ________ in order to tell the cells of the body to start taking in and storing glucose.
low; glucagon
high; glucagon
low; insulin
high; insulin
A diabetic's blood sugar cannot be controlled because their pancreas can not produce enough insulin. To treat the illness, a person must keep track of their blood sugar levels and, if they are too high, inject insulin. What treatment do you think they'd require for low blood sugar?

- Which of the following is a hormone which causes an increase in blood-glucose concentration? pancreas glycogen insulin glucagonarrow_forwardOne role of the pancreas is to help regulate blood glucose levels. Two types of cells in the pancreas, beta and alpha, serve as sensors to detect changes in blood glucose levels. High glucose levels cause beta cells to increase the amount of insulin given off by the pancreas. The insulin triggers body cells to take in glucose and the liver to store excess glucose as glycogen, decreasing the blood glucose level. On the other hand, low glucose blood levels trigger alpha cells to signal for glycogen to free up stored glucose from your liver, thus increasing the blood glucose level. (4 points) 1. What type of feedback mechanism is this, positive or negative? Explain your answer based on the description of the mechanism. Blood glucose levels change throughout the day. Explain what causes these changes and describe how these feedback cycles work together to maintain a dynamic homeostasis. III. Predict what will happen to this feedback mechanism and then to a person's body if the beta cells…arrow_forwardA number of hormones in the body are responsible for controlling blood glucose levels. 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
- 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.arrow_forwardFigure 16.14 Goiter, a disease caused by iodine deficiency, results in the inability of the thyroid gland to form T3 and T4 . 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. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. d. Hypothyroidism, resulting in weight loss, profuse sweating and increased heart rate.arrow_forwardindividually, growth hormone and cortisol each cause a small amount of lipid breakdown in fat cells. When both hormones are present together they cause a very large amount of lipid breakdown. This is an example of _____. synergistic effects of hormones upregulation of hormone secretion due to negative feedback a possitive feedback loop where hormone secretion continues to increasearrow_forward
- I've been confused about diabetes lately. I know that it's said that the pancreas produces insulin, but someone said that actually the pancreas produces beta and alpha cells that signals for the production of insulin or release of glucagon from another organ/gland. Which is it?arrow_forwardGlucagon binds to receptors on its target tissues. What happens next? The beta-cells of the pancreas take up glucose from the blood thereby causing blood glucose levels to drop. O The liver takes up glucose from the blood, converting it to glycogen. O The cells of the body take sugar from the blood and use it. The liver breaks down glycogen releasing glucose into the blood.arrow_forwardIf you chug water when you’re hungry, you’ll temporarily feel full because of the _________ signaling pathway, but you’ll stay full if you eat a bacon (fat), egg (protein), and cheese sandwich (bread=sugars) because of the __________ signaling pathway.

- The regulation of the blood glucose level represents an important feedback loop in the hu- man body. After a meal, the blood glucose level becomes elevated, stimulating beta cells of the pancreas to release insulin into the blood. Excess glucose is then converted to glycogen in the liver, reducing blood glucose levels. Which of the following represents the stimulus in this feedback loop? A conversion of glucose into glycogen B с D elevation of the blood glucose level decrease in the blood glucose level release of insulin by the pancreasarrow_forwardThe majority of the pancreas has the primary function of secreting digestive enzymes, not hormones.
