Introduction

Insulin is the biological chemical that works as an effect to lower blood glucose levels in the blood. It consists of two amino acid chain linked together by disulfide bonds. It is released by beta cells of the pancreatic cells. The beta cell releases this protein when it senses a rise in our blood sugar level or after we have just eaten. After being made by the beta cells in the pancreas, insulin travels down to the body 's tissue cells to be taken up by the body 's cell. Insulin also stimulates glycogen formation in the liver. In the liver, glucose is converted to glycogen which can then be stored in the body for later uses. The uptake of the sugar by the body’s cells reduces the blood glucose sugar in the body, bringing back

This test tube glass was counted as the water bath that we used to heat the Benedict reagent solution. After that, we got a metric ruler, and we marked off six tubes each with at least 1 cm at the top and 2 cm at the bottom. The metric ruler mark represents the volume of serum and reagent that would use in the experiment. We labeled each test tube according to the blood vessel where we got each sample serum from. Then we marked on the test tube with a marking pen whether each of the serum was postprandial (after eating) or fasting (before eating). We filled the test tube according to its label. We filled this tubes to the first mark and placed it on the on the test tube rack. We added the Benedict reagent solution to the second mark. We heated the all three postprandial samples at the same time in the water bath and recorded the time each of the postprandial samples took to change color. We repeated the same thing for the three fasting samples and recorded each of the response time it took for them to change color. Lastly, we disposed of all the used Benedict reagent …show more content…
It was hypothesized that glucose would be taken up first in the mesenteric to the hepatic portal and then the hepatic vein in the fed phase and the reverse in the fasting phase.In the data above it shows that mesenteric artery had the largest amount of glucose followed by hepatic vein and then the hepatic portal vein being the least in the fed phase. In the fasting phase, the hepatic portal vein had the largest amount of glucose followed by the mesenteric artery and finally the hepatic vein. Possible sources of error to have occurred in this lap was the variability of the color changes between the vessels because color has a ray of different shades it 's hard to pinpoint what shade of color the vessels represent. Also, the amount of Benedict that was put in each serum also play an influence, because each drop wasn 't measured to be the same, the amount of Benedict could have disrupted the data collected. For people with hypoglycemia in the hospital setting, blood glucose is evaluated by blood glucose test are administered to the patients to check their blood glucose level. Testing the blood glucose determined either or not the patients should be treated for hyperglycemia (high blood glucose) or hypoglycemia (low blood glucose). Blood glucose can also be determined by laboratory instrument and point of care bedside glucose meter for the convenience of the
