Textbook Question
Chapter 46, Problem 2S
Suppose that you wanted to develop a new treatment for obesity based on the hormone leptin. What structures in the body produce leptin? What does it do? Should your treatment cause an increase in blood levels of leptin or a decrease? Could this treatment affect any other systems in the body?

Which statement best describes the relationship between the hypothalamus and obesity?
Select an answer from the options below
The hypothalamus stimulates the gene mutation that causes addiction, which contributes to overeating and obesity.
The structure of the hypothalamus is changed by high-fat diets, which makes it harder for the body to regulate its weight.
The hypothalamus controls the thyroid gland, which causes one to rapidly gain weight.
The hypothalamus triggers the amygdala, which produces highly enjoyable feelings that are eventually associated with food.
A group of students are participating in a 24-hour fast to raise money for the foodbank. Fasting refers to refraining from eating for a period of time. Select the answer that describes how the students’ bodies would respond to maintain homeostasis.
Select one:
a. The beta cells of the islets of Langerhans are producing glucagon to decrease blood glucose levels.
b. The alpha cells of the islets of Langerhans are producing insulin to increase blood sugar levels.
c. The alpha cells of the islets of Langerhans are producing glucagon to increase blood glucose levels.
d. The beta cells of the islets of Langerhans are producing insulin to decrease blood sugar levels.
The chemical bisphenol-A (BPA) is used to make plastic bottles and to line cans. Evidence from animal experiments and epidemiological studies indicates that the risk of obesity rises with increased BPA intake. How might the endocrine-disrupting effects of such a chemical influence body weight?

- Answer Human Nutrition If you consume more protein than you need, the excess amino acids are stored as fat. What is one thing you CAN do to change your body so that your protein stores are greater? Hormones + exercise: Be able to explain the connection between epinephrine and fat. Where is epinephrine secreted? How does epinephrine help a person who has been exercising for longer than 20 minutes continue exercising? Hormones + exercise: Is insulin needed for exercise activity? Does your body make more or less insulin while you exercise? Be able to summarize effects of hormones + exercise: As blood glucose levels drop during exercise, there is less glucose in the blood available to enter cells and provide energy. The body needs to bring glucose into the blood, so glucose can travel to and enter the cell. What signals the liver and fat cells to release stored energy as glucose? What is the form of that stored energy in the liver? in fat cells? Be able to list the factors that…arrow_forwardAt Kate's next appointment, Paula showed Kate how to use a glucose meter. She instructed Kate to measure her blood glucose level twice a day before and after breakfast and dinner. Paula explains to Kate that her pre-meal blood glucose level should be 110 mg/dLmg/dL or less, and if it increases by more than 50 mg/dLmg/dL, she needs to lower the amount of carbohydrates she consumes. Kate and Paula proceed to plan several meals. Because a meal should contain about 45 to 60 gg of carbohydrates, they combined fruits and vegetables that have high and low levels of carbohydrates in the same meal to stay within the recommended range. Kate and Paula also discuss the fact that complex carbohydrates in the body take longer to break down into glucose and, therefore, raise the blood sugar level more gradually. Kate increased her exercise to walking 30 minutes twice a day. She began to change her diet by eating 6 small meals a day consisting of more fruits and vegetables without starch such as green…arrow_forwardHunger, satiety and feeding are regulated by neural circuits. Outline the specific neural circuits and molecules that control appetite and feeding behaviours. Discuss how appetite-regulating neural circuits could be utilised to treat obesity and type 2 diabetes, giving examples of such treatments. Use figures and diagrams to illustrate your answer.

- Which of the following statements is true about the well-fed state? O a. Liver glycogen is synthesized from polymerization of glucose. b. Mobilization of triacylglycerols from adipose provides fatty acids to be oxidized and precursors for ketone bodies. O C. Insulin decreases. d. Glucagon and epinephrine increase. O e. Synthesis of proteins and fat is inhibited.arrow_forwardCan you answer all the parts to following question, true or false: Q31: A: Complex carbohydrates are broken down by carboxylases in both the mouth and the small intestine (True or False) B: Glycolysis requires the input of energy in order to release energy from glucose (True or False) C: Anorexic hormones signal the body that it is in a fed state (True or False) D: The dependence of hunger on the ratio between insulin and glucagon is an example of signal integration (True or False)arrow_forwardWhen a person fasts for days or weeks the body must compensate by changing proteins (muscle) and fats (adipose) into glucose. What is the name of this homeostatic process and what hormone stimulates this process? A. glycogenolysis stimulated by insulin B. glucohydro-attenuation stimulated by adrenalin C. gluconeogenesis stimulated by cortisol D. carbo-redemtion stimulated by cortisol. arrow_forward
- The human body tries to maintain body mass as best as it can. To that end it has a way of regulating food intake. What two hormones control appetite? Which was knocked out in mice and drove obesity? Why did it cause the mouse to be obese?arrow_forwardEvidence from animal experiments and epidemiological studies indicates that the risk of obesity rises with increasedb isphenol-A (BPA) intake.

- What hormone regulates the short term system related to hunger and satiety? Select one: O a. Insulin O b. Leptin O c. Glucagon O d. ghrelinarrow_forwardWhich two statements below accurately describe the roles of insulin and glucagon in maintaining metabolic homeostasis? Select 2 correct answer(s) insulin inhibits glucose uptake in the brain insulin stimulates glucose uptake in muscle cells insulin stimulates glucose release from liver cells Oglucagon stimulates glucose release from muscle cells glucagon increases blood glucose levels in between meals glucagon stimulates glucose uptake in liver cellsarrow_forwardThe hormone insulin enhances the transport of glucose (sugar) from the blood into most body cells. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? A decrease in blood glucose concentration stimulates insulin secretion, which in turn further towers blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn further increases blood glucose concentration. None of the preceding is correct.arrow_forward
