Insulin is secreted by beta cells‚ which are normally located at the pancreas. When the amount of glucose in the blood increases‚ the stimulus for insulin secretion triggered. The insulin level secreted

BSC 120 Glucose Effect on Diabetic and Non Diabetic Blood Abstract: This lab was developed to investigate blood glucose and diabetes. Diabetes is a lifelong chronic disease in which there are high levels of sugar in the blood (Diabetes). The spectrophotometer was applied to this lab to determine the absorbance of blood glucose in diabetic and non-diabetic blood samples. In order to prove this‚ tests were conducted by taking the blood samples at different times right before a meal was eaten then
