Although cholesterol has gotten a bad name, in the human body it is important, is the precursor of several steroid hormones and vitamin D. is a lipid component of all cell membranes. The α-glycerol-phosphate pathway for triacylglycerol synthesis is outlined in Chapter 8. You commonly fast overnight, but skipping meals during the day puts your body in the postabsorptive state as well. Thanks for the A2A Liver glycogen is associated with the body maintaining proper blood glucose concentrations in the post-absorptive state (fasting). C. glucagon levels are elevated. Additionally, the liver converts lactic acid released from skeletal muscle back into glucose. 262. Starvation Glycogen is formed in the liver during the absorptive state. 85) During the absorptive state, under insulin control, the liver takes in glucose and converts it to glycogen, the inert storage form. Levels of blood glucose are elevated. In the absorptive state, the 2–4-hour period after ingestion of a meal, these regulatory mechanisms ensure that available nutrients are captured as glycogen, triacylglycerol (TAG), and protein (Figure 24.20). This phenomenon is due largely to greater lipid and lower carbohydrate availability, as plasma non-esterified fatty acid (NEFA) concentrations rise in response to lower insulin and higher counter-regulatory hormone … 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). In the ABSORPTIVE state, glucose is NOT a. The digestion of carbohydrates begins in the mouth, whereas the digestion of proteins and fats … E. All of these answers are correct. B. adipocytes contribute fatty acids to the circulation. From a metabolic point of view, which of the following is true? All of the following occur during the postabsorptive state, except that? 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). C) skeletal muscles break down glycogen. The liver forms glycogen and insulin levels are elevated. 18. lactate and pyruvate secretion into the bloodstream by the muscles increases. Ketoacids are the liver’s main source of energy in the absorptive state. Excess amino acids and dietary fat are also converted to triglycerides and stored. B) adipocytes contribute fatty acids to the circulation. If both are present in relatively high amounts, then the excess of insulin promotes the glucose conversion into glycogen for storage in the liver and muscle cells. In the absorptive state, a fraction of the absorbed amino acids is taken up by the liver (Fig. These relationships are outlined in Figure 9.1. PostabsorptiveState" "As"the"absorptive"state"comes"to"an"end,"enterocytes"stop"providing"glucose"to"the"hepatic" portal"circulation. A) period when the metabolic rate is lowest B) postabsorptive state C) starvation period D) absorptive state. 9.1) and converted to ketoacids that are oxidized via the citric acid cycle and other pathways. Triglycerides - Chylomicrons, the main product of fat digestion, are first broken down to fatty acids and glycerol through hydrolysis using Lipoprotein lipase. Amino acids and fats are used to form degraded protein, and small amounts are used to provide ATP. During the absorptive state of metabolism, glycogen in muscle cells is broken down to glucose, which is used for energy. Glycogen formation is called glycogenesis, which takes place depending on the demand for glucose and ATP. & During this state, the body must rely initially on stored glycogen. This is a very important point: During the absorptive ... glycogen in liver and skeletal muscle, and (3) storage as fat in adipose tissue. Liver glycogen is broken down to maintain a constant level of glucose in the blood; muscle glycogen is broken down to provide glucose to the muscle during vigorous exercise.

Carbohydrates are first used for ATP synthesis with excess stored as glycogen or triglycerides in the adipose tissue. Fatty acids incorporated into triglycerides in the adipose tissue come from all of the following … The glucose comes from the glycogenolysis or gluconeogenesis. During this interval, transient increases in plasma glucose, amino acids, and TAG occur, the last primarily as components of chylomicrons synthesized by the intestinal … The digestion of carbohydrates begins in the mouth, whereas the digestion of proteins and fats begins in the stomach and small intestine. Nutrient processing in the absorptive state The remaining glucose is taken in for use by body cells or stored in skeletal muscle as glycogen. Figure 24.5.2 – Postabsorptive State: During the postabsorptive state, the body must rely on stored glycogen for energy, breaking down glycogen in the cells and releasing it to cell (muscle) or the body (liver). 43. During the absorptive state, anabolic reactions are favored. 14. Glycogen stored in the liver is a source of glucose that is mobilized between meals to prevent low blood sugar, whereas muscle glycogen is stored as an energy reserve for muscle contraction. The absorptive state, or the fed state, occurs after a meal when your body is digesting the food and absorbing the nutrients (anabolism exceeds catabolism). During the absorptive state?
