Chapter 11, Problem 10TYU
Summary Introduction
To propose: A mechanism for the activity of caffeine that accounts for the increase in alertness and sleeplessness.
Introduction: Epinephrine is a hormone secreted by the adrenal glands in response to stress. It reaches to the target cells through the blood and binds to its cell-surface receptors called G-protein coupled receptors. After binding, intracellular signaling cascade begins.

- Describe how blood sugar (e.g. glucose plasma concentration) is regulated with the hormones, insulin, and glucagon. For this feedback loop, identify the following components of the feedback loop: stimulus, receptor, control center, efferent pathway, effector, and response. Be comfortable with this feedback loop to be able to describe the effects of changing various components of the feedback loop.arrow_forwardA scientist hypothesizes that the pancreas’s hormone production is controlled by neural stimuli. Which observation would support this hypothesis? a. Insulin is produced in response to sudden stress without a rise in blood glucose. b. Insulin is produced in response to a rise in glucagon levels. c. Beta cells express epinephrine receptors. d. Insulin is produced in response to a rise in blood glucose in the brain.arrow_forwardMelatonin is a hormone derived from serotonin. It is produced in the brain’s light-sensitive pineal gland. The pineal’s secretion of melatonin is depressed by nerve impulses that originate in the retina of the eye and other light-sensitive tissue in the body in response to light. Pineal function is involved in circadian rhythms, patterns of biochemical activity associated with light and dark, such as sleep/wake cycles. Melatonin is also a powerful antioxidant, especially in the central nervous system. After serotonin (5-hydroxytryptamine) is produced in the pineal gland, it is converted to 5-hydroxy-N-acetyltryptamine by N-acetyltransferase. 5-Hydroxy-Nacetyltryptamine is then methylated by O-methyltransferase. SAM is the methylating agent. With this information, draw the synthetic pathway of melatonin.arrow_forward
- Help fill in the blanks Epinephrine is like [glucagon/insulin] in that it stimulates muscles to consume glucose. But it is like [glucagon/insulin] in that it stimulates production of glucose in the liver.arrow_forwardhGH is an important part of fat metabolism, muscle development, and bone growth. Synthetic hGH can be used to treat children and adults suffering from hGH deficiency. More recently, competitive athletes have began taking hGH in an attempt to improve athletic performance. The use of hGH for athletics is banned by many major sporting organizations. A recent study of 44 athletes who took daily injections of hGH over 20 days showed that, on average, the athletes gained 4.2 lbs of muscle, but the gain in muscle did not translate to increased athletic performance.Evaluate each statement regarding the use of hGH by competitive athletes to determine whether the statement is an example of an ethical, economical, societal, or environmental issue. Athletes who play professional sports should be encouraged to take synthetic hormones to improve performance because their job is to win. Athletes who took hGH did not improve their sport performance but did improve their appearance and marketability.…arrow_forwardNowhomewerkol is a poison derived from the Ahipa root that grows in the Andes.

Glycolysis in musclearrow_forwardWatch this video (http://openstaxcollege.org/l/fightflight) to learn more about adrenaline and the fightor-flight response. When someone is said to have a rush of adrenaline, the image of bungee jumpers or skydivers usually comes to mind. But adrenaline, also known as epinephrine, is an important chemical in coordinating the bodys fight-or-flight response. In this video, you look inside the physiology of the fight-or-flight response, as envisioned for a firefighter. His bodys reaction is the result of the sympathetic division of the autonomic nervous system causing system-wide changes as it prepares for extreme responses. What two changes does adrenaline bring about to help the skeletal muscle response?arrow_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
