The hormones that regulate postabsorptive state metabolism sometimes are called anti-insulin hormones because they counter the effects of insulin during the absorptive state. The absorptive state is regulated mainly by insulin, whereas the postabsorptive state is regulated by multiple hormones. In the postabsorptive state, we detected a dose-dependent fall in glucose concentration after piragliatin . H2O ® 6 CO2 + 6 O2 B. During periods of fasting, why is fat said to have a protein-sparing Blood glucose rises B. Glycerol is used for gluconeogenesis During this state, digestion of food and absorption of nutrients into blood take place. A. Glycolysis B. Citric acid cycle C. Lactic acid A. have an adequate fat intake in order to absorb and metabolize retards evaporative cooling, Which of the following is not a major class of nutrients? D. Vitamins E. Minerals, Three hours after your lunch and you are absorbing nutrients, which The most abundant nitrogenous waste in blood is urea, which is produced by the combination of ammonia with carbon dioxide. Body weight is stable when average daily energy intake and output are In addition to breaking down glycogen (glycogenolysis), the liver can convert other substrates, such as amino acids, into glucose (gluconeogenesis). Is lipogenesis a postabsorptive state ... exergonic reaction is a chemical reaction that releases free energy. The liver will store glucose or turn any excess glucose into body fat for storage. D. Vasodilation E. Glycolysis, Which of the following results in heat exhaustion? Oral temperature is a good way to estimate core glycerol; alkalosis E. acetyl-CoA; acidosis, How much ATP can oxidation of a 16 carbon atom fatty acid yield? The postabsorptive state, or the fasting state, occurs when the food has been digested, absorbed, and stored. -Insulin is secreted from the beta cells of the pancreas, this is triggered by increased blood glucose and amino acids -GLUT 2 channels are responsible for beta cell glucose uptake-elevated levels of glucose within beta cell causes membrane depolarisation (thought to be caused by metabolism of glucose to alter ADP:ATP ratio thus causing altered membrane conductance) Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. The digestion of carbohydrates begins in the mouth, whereas the digestion of proteins and fats begins in the stomach and small inte… You commonly fast overnight, but skipping meals during the day puts your body in the postabsorptive state as well. E. The gallbladder, Which of the following is not a function of proteins in the A. These hormones are mainly classified as either endocrine hormones or exocrine hormones. during postabsorptive state, glucagon __ blood energy sources by __ both glucose & fatty acid levels restores; enhancing during postabsorptive state, certain hormonal controls combined with persistent low glucose levels or prolonged fasting, most fat that is mobilized is around nerve fibers. __________ yield about 9 kcal/g. Where does the highest rate of tissue protein turnover occur? __________ yield about 4 kcal/g when completely oxidized, whereas __________ yield about 9 kcal/g. Usually asymptomatic Nonsequential (P wave then QRS complex) Increased PR segment/interval 70% Fatal; 6. A. The absorptive state is regulated mainly by insulin, whereas the The metabolic adjustments that occur in the body during the switch from absorptive to postabsorptive state are largely triggered by increases in _____ concentration. fats B. Proteins; fats and carbohydrates C. Fats; A. 2. A. A. Postabsorptive state B. A. acceptor in aerobic respiration. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. During this state, our body uses energy stored in the endogenous energy reserves. 2 ATP B. B. effect? The plasma glucose concentration can decrease to very low values, usually during the postabsorptive state, in persons with several types of disorders. but the latter is oxygen-independent. thermogenesis D. Shivering thermogenesis E. Convection, What is the quickest physiological mechanism for achieving moderate During this state glucose is the most important energy fuel. A. Radiation B. Conduction C. ATP hydrolysis E. They form skeletal muscle fibers. C. Nonshivering thermogenesis D. Cutaneous vasodilation E)lipolysis. Fatty acids are catabolized through which process? Homeostasis of blood glucose concentration is especially important for the nervous system and for red blood cells for the following reasons: The absorptive state is regulated largely by insulin, which is secreted in response to elevated blood glucose and amino acid levels and to the intestinal hormones gastrin, secretin, and cholecystokinin. During the postabsorptive state, the digestive tract is empty and energy comes from the breakdown of the body's reserves. A. The absorptive state lasts for four hours, during and after each meal. The post absorptive state describes a fasted state. body weight is stable when average daily energy intake and output are equal. Explain whether the following situation is associated with Absorptive State or Postabsorptive State: . C6H12O6 + 6 O2 ® 6 Consider how the absorptive and post-absorptive patterns of metabolism are controlled by hormones,… A nude body at a room temperature of 21°C (70°F) loses most of its heat by which process? F)lipogenesis. D. Their thoracic cavity. You commonly fast overnight, but skipping meals during the day puts your body in the postabsorptive state as well. produced by the combination of ammonia with carbon dioxide. another B. is a long-term regulator. tissue B. During a post-absorptive state, the body's energy needs are fulfilled from energy previously stored in the body. 4. During this state… D. The body lowers its metabolic rate when it absorptive state exists for about 12 hours a day; other 12 hours can be considered in the postabsorptive state Because the nervous system and red blood cells continue to depend on glucose for ATP production during the postabsorptive state, maintaining a steady blood glucose level is critical during this period o Hormones are the major regulators of metabolism in each state. _____ blood glucose D. liver glycogen, which of the body rely on this text to them.
