Explain how the electron trans- port system is involved in this process. In mi- tochondria, each NADH yields 3 molecules of ATP, whereas each FADH2 yields just 2 molecules of ATP. How are lipids catabolized in the body? C) insulin. Acetone has a fruity aroma, so her breath would also smell fruity. What effect does peripheral vasoconstriction on a hot day have on an individual's body temperature? Catabolism is the breakdown of organic molecules into simpler components, accompanied by the release of en-. Energy from the stepwise passage of electrons (from H atoms) along the cytochrome molecules is used to pump hydrogen ions from the matrix into the intermembrane space. The major groups are chylomicrons, which consist of 95 percent triglyceride, are the largest lipoproteins, and carry absorbed lipids from the intestinal tract to the blood- stream; very low density lipoproteins (VLDLs), which consist of triglyceride, phospholipid, and cholesterol, and transport triglycer- ides to peripheral tissues; intermediate-density lipoproteins (IDLs), which are intermediate in size and composition between VLDLs and LDLs; low-density lipoproteins (LDLs, or "bad cholesterol"), which are mostly cholesterol and deliver cholesterol to peripheral tissues; and high-density lipoproteins (HDLs, or "good choles- terol"), which are equal parts protein and lipid (cholesterol and phospholipids) and transport excess cholesterol to the liver for stor- age or excretion in bile. It appears that Jill is suffering from ketoaci- dosis as a consequence of her anorexia. 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 One of the ketones formed is acetone, which can be eliminated through the lungs. During this state, the body must rely initially on stored glycogen. The digestion of carbohydrates begins in the mouth, whereas the digestion of proteins and fats begins in the stomach and small inte… What hormone is used to turn glucose into fat? Glycogenolysis, Lipolysis, Gluconeogenesis, Ketogenesis. absorptive state: The period during digestion when anabolism exceeds catabolism. 16. You commonly fast overnight, but skipping meals during the day puts your body in the postabsorptive state as well. A) insulin. During the postabsorptive state tissues other than the brain utilize fatty acids for energy, and the liver produces glucose by breaking down glycogen to glucose and converting other substrates to glucose via gluconeogenesis. What is oxidative phosphorylation? What hormones are used to turn amino acids into proteins? In LIPOLYSIS, lipids are broken down into what? a. lipogenesis b. to store excess glucose by glycogenesis c. to mobilize glucose reserves by glycogenolysis d. glycolysis e. … Explain the processes that regulate glucose levels during the absorptive and postabsorptive states; Explain how metabolism is essential to maintaining body temperature (thermoregulation) Summarize the importance of vitamins and minerals in the diet; Figure 1. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 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). A function of the liver during the postabsorptive state is _____. During the postabsorptive state, blood glucose begins to decline, triggering the liver to release glu- cose produced through glycogenolysis and gluconeogenesis. Why are high-density lipoproteins (HDLs) considered beneficial to health? The postabsorptive state, or the fasting state, occurs when the food has been digested, absorbed, and stored. The end result of PA state, the plasma glucose increases/decreases? ; Kreb’s cycle: The Kreb’s cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidization of acetate derived from carbohydrates, fats and proteins into carbon dioxide. The postabsorptive state, or the fasting state, occurs when the food has been digested, absorbed, and stored. How would a decrease in the amount of bile salts in the bile affect the amount of vitamin A in the body? A diet deficient in pyridoxine (vitamin B6), an important coenzyme in de- aminating and transaminating amino acids in cells, would interfere with the body's ability to metabolize proteins. The primary role of the citric acid cycle in ATP production is to transfer electrons from substrates to coenzymes. (a) fasting, (b) postabsorptive, (c) absorptive, (d) stress, (e) bulimic. You commonly fast overnight, but skipping meals during the day puts your body in the postabsorptive state as well. What hormone is used to turn glucose into glycogen? What is a lipoprotein? Why are vitamins and minerals essential components of the diet? gluconeogenesis is stimulated by decreased levels of. This is probably the cause of her arrhythmias. As the body progresses from the absorptive to the post absorptive state, only ___ continues to burn glucose while every other organ in the body mostly switches to fatty acids. How do the absorptive and postabsorptive states maintain normal blood glucose levels? In large amounts, this lowers the body's pH. The liver also stores energy in the form of glycogen. The ketones are also converted into keto acids such as acetic acid. Glycogen formation is called glycogenesis, which takes place depending on the demand for glucose and ATP.
