Exercise 42. Although students within each treatment group consume the same meal, they display variability in postprandial blood glucose levels. Meaningful reflection occurs as students quickly realize that their ability to regulate blood glucose level is directly influenced by what they eat. Williamson County Sheriff Chody, Although students are only asked to statistically compare the means of their treatment group to the means of the OGTT group, there were significant differences between meal treatments at various time points (Table 5). Lab Report: Exercise 9: The Digestive System. Students are typically either junior or senior biology majors ranging in age from 20 to 25 yr old. Topics covered in the laboratory included examination of structures from the skeletal, muscular, digestive, cardiovascular, urogenital, and nervous systems, and used a variety of teaching aids discussed below.

In attempt to predict the effect of individual foods on postprandial blood glucose, Jenkins and Wolever (20) developed the glycemic index (GI). 3). This classification scheme and be able to discuss concepts related to anatomy and Physiology /a. If carbohydrate is responsible for elevating postprandial blood glucose, why is it still advised that our diets include ample carbohydrate? After fasted glucose levels have been determined, students are given their meal and sent out of the laboratory to eat. Respiratory System. Write labels on the right side only. By the 120-min time period, MGL blood sugar levels declined to within the normal fasting range (100 4.7). 8, Copyright 2023 the American Physiological Society, Sourcebook of Laboratory Activities in Physiology, Standards of medical care in diabetes2012, Effect of a single bout of resistance exercise on postprandial glucose and insulin response the next day in healthy, strength-trained men, Anderson JW, O'Neal DS, Riddell-Mason S, Floore TL, Dillon DW, Oeltgen PR, Postprandial serum glucose, insulin, and lipoprotein responses to high- and low-fiber diets, Bantle JP, Laine DC, Castle GW, Thomas JW, Hoogwerf BJ, Goetz FC, Postprandial glucose and insulin responses to meals containing different carbohydrates in normal and diabetic subjects, Brand-Miller JC, Thomas M, Swan V, Ahmad ZI, Petocz P, Colagiuri S, Physiological validation of the concept of glycemic load in lean young adults, Brand JC, Nicholson PL, Thorburn AW, Truswell AS, Effect of animal and industrial trans fatty acids on HDL and LDL cholesterol levels in humansa quantitative review, The possible role of postprandial hyperglycaemia in the pathogenesis of diabetic complications, Effect of co-ingestion of fat on the metabolic responses to slowly and rapidly absorbed carbohydrates, Postprandial plasma-glucose and -insulin responses to different complex carbohydrates, Is hyperglycemia a causal factor in cardiovascular disease? 3.

Students are also instructed to monitor others in their laboratory group. Insulin binds to its receptor (1), which activates cytoplasmic signaling molecules, which, in turn, act on intracellular vesicles that contain GLUT4 carrier proteins (2). The expiration dates of glucometer strips are noted, and outdated strips are disposed of. Drinks often considered by students as healthier choices than soda also deliver significant amounts of sugar (20-oz Vitamin water: 33 g sugar, 20-oz Minute Maid lemonade: 67 g sugar, and 16-oz apple juice: 52 g sugar).
