Nutrient processing in the absorptive state. The term metabolism is best defined as _____. As previously explained, fatty acids can be converted into acetyl CoA and processed through the Krebs cycle to make ATP. After a few days, however, ketone bodies are created from fats and serve as the preferential fuel source for the heart and other organs, so that the brain can still use glucose. Pyruvate, lactate, and alanine from muscle cells are not converted into acetyl CoA and used in the Krebs cycle, but are exported to the liver to be used in the synthesis of glucose. By the end of this section, you will be able to: You eat periodically throughout the day; however, your organs, especially the brain, need a continuous supply of glucose. muscle proteins are used as an energy source. Fat soluble nutrients pass through villi and enter the lymph. The strategy of eating starchy foods for several days before an athletic event is known as. During the absorptive state, our body digests foods and absorbs nutrients into the blood. As blood glucose levels rise, the pancreas releases insulin to stimulate the uptake of glucose by hepatocytes in the liver, muscle cells/fibers, and adipocytes (fat cells), and to promote its conversion to glycogen. oxidative phosphorylation leads to ATP formation.

Sweating produces heat loss largely by __________. All of the following occur during the postabsorptive state except that. The glucose is released into the bloodstream to serve as a fuel source for cells throughout the body. Once these stores are fully depleted, proteins from muscles are released and broken down for glucose synthesis. Labeled statements: You can give a statement a label and then use the goto keyword to jump to the labeled statement. Solution.pdf Next Previous. (C) The slaves of the Confederacy were freed. fatty acids. The liver, which normally absorbs and processes glucose, will not do so after a prolonged fast. (See the example in the following row.) A. Amino acids provide energy at a steady pace throughout the postabsorptive state. The ingestion of food and the rise of glucose concentrations in the bloodstream stimulate pancreatic beta cells to release insulin into the bloodstream, where it initiates the absorption of blood glucose by liver hepatocytes, and by adipose and muscle cells. glucose recently absorbed into the bloodstream It is a very important hormone since it controls the levels of electrolytes such as potassium and sodium in the blood plasma. B. Beta-oxidation is a series of metabolic reactions in which amino acids oxidized to yield energy. Which of the following statements best describe the role of South Carolina in decision of southern states to secede from the union? What are the other fat-soluble vitamins? An absorptive state occurs during the period within four hours of food consumption. 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). lactic acid. THE ABSORPTIVE AND POST-ABSORPTIVE STATES Chapter objectives After studying this chapter you should be able to: 1. Which of the following best describes how these conditions are related?

The remainder is lost as __________. Which of the following statements best describes the status of Native Americans at the end of the 19 th century? A post-absorptive state differs from an absorptive state. D) fatty acids supplied from triglycerides. Inorganic ions released through the dissociation of electrolytes are called. Pregnant or lactating women like Justine actively synthesize N compounds. Figure 2. Because glucose levels are very low during starvation, glycolysis will shut off in cells that can use alternative fuels. As the postabsorptive state begins, glucose levels drop, and there is a corresponding drop in insulin levels. The empty statement: The empty statement consists of a single semicolon. The United States has shared new environmental technology with developing countries in the hopes that these countries will reduce their carbon emissions.
