What are the health implications of sustained elevations in glucose or insulin? Therefore, the regulation of blood glucose, both fasted and fed, was ideal to meet our objective. Base of the heart. Adv Physiol Educ 33: 209212, 2009. 47.1 1. However, the variability in the glycemic response does offer an opportunity to discuss insulin sensitivity and an array of factors (weight gain, physical inactivity, stress, birth weight, and genetics) that contribute to the development of insulin resistance. No differences existed between fasting levels, and therefore fasting levels are not reported. an experiment, or a conclusion: Students have previously learned that carbohydrate is digested and absorbed primarily as glucose (or converted to glucose by the liver). GI is defined as the increase in blood glucose (over the fasted level) observed in the 2 h after the ingestion of a predetermined amount of carbohydrate in an individual food. Requiring students to write their hypotheses addresses the objective of having students predict postprandial blood glucose levels based on the GL of the meal. At 60 min, blood glucose levels peaked for the OGTT group (151 8.4), whereas the HGL, MGL, and LGL groups showed a decline from 30-min levels. The Urinary System. This approach has been more effective for systems such as the cardiovascular and respiratory systems, where measures such as heart rate, blood pressure, breathing frequency, and lung volumes can be obtained noninvasively. Completion of this laboratory as written requires 2.53 h. To shorten the time required, students could be asked to eat at a set time before class or assess postprandial sugars for a shorter time period.

Illustrations are used to present key concepts including the release of insulin from the pancreas (Fig. Science. Students also discover that the presence of fat and protein in the meal likely serves to moderate the postprandial response as fat delays gastric emptying and tends to flatten the postprandial plasma glucose response (10). Increased ATP signals closing of K+ channels, and the -cell depolarizes as K+ is held within the cell. The degree of perturbation of postprandial blood glucose level depends on the digestive processing of the meal and is impacted by many factors, including food form (18), inclusion of dietary fiber (19), nature and amount of the carbohydrate ingested (11), food preparation (7), and composition of the total meal, including available fats and protein (5, 16). Each meal was independently compared with the OGTT group, and significant differences between the meal and OGTT groups at each time point is shown in Fig. Bleach (diluted 1:10). You are responsible for the identification of all . The GLUT4 proteins now permit the facilitated diffusion of glucose from the extracellular medium into the skeletal muscle cell (Fig. \mathrm{SO}_3{ }^{2-} Care must be taken to make sure lancets are replaced before each finger stick, and one might advise using disposable single-use lancets to avoid cross-contamination. This laboratory exercise provides a systems approach to digestive and regulatory processes through the exploration of postprandial blood glucose levels. Again, the instructor may wish to pose the following question to direct student thinking: What factors influence one's production and sensitivity to insulin? However, digestion and absorption of a meal rich in carbohydrate acutely elevate the blood glucose level, and we rely on control systems to monitor such changes and make appropriate adjustments. Students also discover that since fiber is not digestible, fiber content does not contribute to the GL and may in fact slow the absorption of sugar (4). Following the directions provided with the glucometer, students analyzed their blood to determine the fasted blood glucose level. approved final version of manuscript. 2. There should be sufficient quantity to mix the required number of oral glucose solutions (75 g/person).
