It also helps regulate a person’s blood pressure since it influences the amount of sodium and w… Depending on the amounts and types of nutrients ingested, the absorptive state can linger for up to 4 hours. During the absorptive state A. the principal regulatory hormone is glucagon. This prevents the continued breakdown of proteins that serve as carbon sources for gluconeogenesis. Which of the following explanations best describes why? 0 votes. Once inside these cells, glucose is immediately converted into glucose-6-phosphate. The body can synthesize the carbon chains of the N compounds but must obtain nitrogen atoms either by recycling N compounds or by absorbing nitrogen from the diet. Inadequate exposure to sunlight could result in decreased amounts of vitamin ________ in the body. Despite the importance of nitrogen, the body neither stores nitrogen nor maintains reserves of N compounds. Lipoproteins that carry mostly cholesterol to peripheral tissues are called. answered Oct 16, … B. (a) 1 and 2 (b) 2 and 3 (c) 3 and 4 (d) 4 and 5 (e) 1 and 5. Aldosterone is one of the steroid hormones that are produced in the human body. After these stores have been replenished, excess glucose that is absorbed by the liver will be converted into triglycerides and fatty acids for long-term storage. Muscle will be spared to prevent the wasting of muscle tissue; however, these proteins will be used if alternative stores are not available. Carbohydrates - Simple sugars are sent to the liver where they are converted to glucose.The glucose then travels to the blood or is converted to glycogen and fat (triglyceride). The absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (catabolism exceeds anabolism). What provides energy required to produce the molecule indicated by the red arrow? A. Liver glycogen stores are utilized to supply the blood with glucose even during long-term fasting . If not, the excess glucose is stored as glycogen in the liver and muscle cells, or as fat in adipose tissue; excess dietary fat is also stored as triglycerides in adipose tissues. c. The small intestine is about 25-feet long. During the absorptive state, the stomach and intestines contain nutrients that are being absorbed by the body. Answer the question(s) below to see how well you understand the topics covered in the previous section. A balanced diet is important to provide the body with all the necessary nutrients to ensure physiological functioning. Which of the following statements best describes what next happens to pyruvate? ________ carry excess cholesterol from peripheral tissues to the liver. A(n) ________ protein is deficient in one or more of the essential amino acids. Digestion begins the moment you put food into your mouth, as the food is broken down into its constituent parts to be absorbed through the intestine. (D) All slaves who joined the Union army would be freed. (1) aerobic cellular respiration, (2) glycogenesis, (3) glycogenolysis, (4) gluconeogenesis using lactic acid, (5) lipolysis. During any given day, your metabolism switches between absorptive and postabsorptive states. Check out the book .. Where do electrons go, The end products of aerobic respiration are, The process of synthesizing glucose from noncarbohydrates is called, The process of glycogen formation is known as. Figure 2 summarizes the metabolic processes occurring in the body during the postabsorptive state. absorptive state. Best Answer 100% (6 ratings) Previous question Next question Transcribed Image Text from this Question. This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. Once these stores are fully depleted, proteins from muscles are released and broken down for glucose synthesis. Many important compounds in the body contain nitrogen atoms (N compounds), including amino acids, the bases of RNA and DNA, creatine, and porphyrins. Which of these provides the greatest yield of ATP? THE ABSORPTIVE AND POST-ABSORPTIVE STATES Chapter objectives After studying this chapter you should be able to: 1. 12. There are three main metabolic states of the body: absorptive (fed), postabsorptive (fasting), and starvation. As you will see, muscle protein can be catabolized and used as fuel in times of starvation. The term metabolism is best defined as _____. What is the original source of all of the CO2 molecules in the process shown in this diagram? The concentration of circulating thyroid hormones is an indirect method of determining BMR. Inorganic ions released through the dissociation of electrolytes are called. asked Oct 16, 2015 in Anatomy & Physiology by DebiWo. Ketone body accumulation caused acidification dropping the pH too low, resulting in coma. Describe how ketones are synthesized. Which of these statements is NOT true about beta-oxidation? The condition where the blood pH drops because of ketone bodies in the blood is called __________. 9. However, due to the demands of the tissues and organs, blood glucose levels must be maintained in the normal range of 80–120 mg/dL. Blood sugar is high. Glycolysis yields two molecules of pyruvate. C) glucose supplied from glycogen. The second priority is the conservation of amino acids for proteins. What percent of energy released from catabolism is lost as heat? Sep 26 2019 01:30 PM. Because glucose levels are very low during starvation, glycolysis will shut off in cells that can use alternative fuels. Which of the following statements correctly describes protein metabolism during the postabsorptive state? lactic acid. This mineralocorticoid hormone is secreted from the adrenal gland which sits on top of the kidneys. glycogen form that glucose assumes when it is stored, insulin: hormone secreted by the pancreas that stimulates the uptake of glucose into the cells, postabsorptive state: also called the fasting state; the metabolic state occurring after digestion when food is no longer the body’s source of energy and it must rely on stored glycogen, http://cnx.org/contents/14fb4ad7-39a1-4eee-ab6e-3ef2482e3e22@8.25, Describe what defines each of the three metabolic states, Describe the processes that occur during the absorptive state of metabolism, Describe the processes that occur during the postabsorptive state of metabolism, Explain how the body processes glucose when the body is starved of fuel. (B) The practice of slavery was ended in the border states only. They result from a psychological problem that causes inadequate or excessive food consumption. What can the body do naturally in order to reduce body temperature, not necessarily to the point of hypothermia, but rather to prevent overheating?
