Discuss the role of the nervous and endocrine systems in temperature regulation stress response fight to flight and blood glucose regulation
Step by step
Solved in 3 steps
- An example of negative feedback in a homeostatic system is: seeing a drug-related cue results in drug-seeking restoring the desired blood sugar level turns off the hormonal response activation of the amygdala increases activation of the HPA axis. insulin release after eating a meal.Which of the following statements about glucose regulation is FALSE? *Glucagon is released by the alpha cells when blood glucose levels are low.Insulin is released by the beta cells when blood glucose levels are high.Glucagon stimulates the formation of glycogen in the liver.Individuals with Type II diabetes produce insulin, but the insulin receptors don’t work.Insulin makes body cells more permeable to glucose.Athletes often use whey products to prepare for competition because whey proteins: Group of answer choices are mild stimulants that produce alertness and reduce reaction time provide all the essential amino acids needed to build new muscle tissue elevate testosterone and estrogen in the blood of male and female athletes, respectively produce rapid weight loss by burning excess body fat and sparing glycogen produce free radicals that promote many of the body's beneficial responses to exercise
- A 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.When the concentration of glucose in the blood falls below a certain level the body issues a signal to allow stored glucose to enter the blood after a short time the body has established a normal concentration of glucose what does this action illustratesDuring intense exercises and when muscles are working harder, our cells metabolize glucose rapidly resulting to oxygen molecules being quickly consumed. Which of the following becomes the human body's coping mechanism in response to limited oxygen supply? faster breathing and lower blood circulation slower breathing and faster blood circulation faster breathing and faster blood circulation slower breathing and slower blood circulation
- An example of negative feedback mechanism is the control of blood glucose levels by insulin. A __________ in blood glucose leads to the pancreas secreting insulin that promotes __________ of glucose from the bloodstream. fall; release fall; removal rise; removal rise; release none of the aboveRestriction of food intake leads to which of the following? An increase in whole body energy expenditure Reductions in resting energy expenditure due in part to reduction in body mass An increase in the thermic effect of food due to lower energy intake Reductions in activity energy expenditure due to increased activity costs associated with a smaller body sizeWhich 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 cells
- The graph shows the blood-glucose levels and insulin levels of an individual. Blood-glucose levels are controlled by a feedback loop that involves the hormone insulin. Which of the following statements best explains the role of insulin in this feedback loop? Insulin controls the blood-glucose level in a positive feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to raise the blood-glucose level even higher. Insulin controls the blood-glucose level in a negative feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to raise the blood-glucose level even higher. Insulin controls the blood-glucose level in a positive feedback loop. As the level of blood glucose rises above a normal set point, the level of insulin increases to lower blood-glucose back to the normal level. Insulin controls the blood-glucose level in a negative feedback loop. As the level of blood glucose…Your immune system has detected an invading bacterial infection. Cytokines are released.
