Blood glucose is the preferred energy source for our bodies. Blood glucose is the preferred fuel source for ATP production and neurons absolutely have to have glucose. Other cells can use alternative nutrients, such as fatty acids, glycerol, and amino acids. Without glucose, neurons cannot function meaning humans could seizure and/or die. There are two hormones secreted by the pancreas that control glucose levels in the body. The first hormone, insulin, is secreted right after the body has had a meal and is in postparandial state. In postparandial state, glucose levels rise. Cells need glucose, so the first …show more content…
The clean test tubes were measured and a mark was made at one and two centimeters to ensure quantities of samples were measured accurately. Three out of the six test tubes were filled to the one centimeter mark with the samples of the hepatic vein, hepatic portal vein, and the mesenteric artery postprandial. The next three test tubes were measured to one centimeter with samples that were extracted from the same areas of the blood vessel system. The difference in the samples was that the second sets of samples were extracted during the fasting state. Water was then added to a beaker and it was set on top of the hot plate. After the water was boiling, Benedict's reagent was placed in to the six test tubes up to two centimeters. The first color of Benedict's reagent was blue. As glucose levels rise, Benedict’s reagent changes in color gradually from blue to yellow to orange to red. The first three test tubes of the blood vessel samples taken from postprandial were placed in the hot water bath. The time was recorded, using a stopwatch, to accurately document when each sample turned red. After each of the three tubes had turned red, and their turning time had been recorded, the tubes were transferred back to the rack and cooled. The final color changes were recorded. The last test tubes with samples …show more content…
The final color of the hepatic portal vein was dark red. The hepatic vein showed color change at 44 seconds with a final color of bright red. The superior mesenteric artery changed color at 51 seconds with a final color of brown. The fasting data with the effective hormone glucagon indicated color change in the hepatic vein at 46 seconds. The final color of the hepatic vein was burgundy. The superior mesenteric artery showed color change at 1 minute and 2 seconds with a final color of light brown. The hepatic portal vein changed color at 1 minute 10 seconds and had a final color of blue/grey indicating little to know
