Regulation of blood sugar in the human bodyCannon (1989) used the term homeostasis to describe the consistency of the internal environment and the integrated regulatory mechanisms are directed at maintaining it. He also stated that this is how the system responds to an emergency by trying to meet sudden external demands that have been placed on the human body (1). Homeostasis is important within the human body because it maintains the optimal environment required for various processes to occur. The cells of the human body are able to acquire energy from lipids; however, nerve cells (neurons) rely completely on glucose. Therefore, the regulation of blood glucose in the human body is necessary to ensure the functioning of the nervous system and enable cellular respiration. (2) Glucose is an organic molecule that will provide a source of energy for the metabolic activities of the human body. It is also a key source of carbon skeletons for biosynthesis. The energy stored in the glucose molecule is released through a process called glycolysis. Glycolysis occurs during respiration. When completely broken down, glucose is converted to adenosine triphosphate (ATP). This allows a manageable amount of energy to be released to power the various biochemical reactions that occur. The two main hormones used to regulate blood glucose concentrations are insulin and glucagon. Figure 1 shows how insulin and glucagon can regulate blood glucose levels. Insulin decreases the concentration of glucose in the blood while glucagon increases it; therefore they are known as antagonist hormones since they are opposites. If the blood glucose concentration is above 70-110 mg/100 ml, the beta cells……in the center of the card……r. This was then repeated after 60 minutes, however during this time the participant would have consumed 600ml of water. One of the readings on the Urilux stick showed whether there was glucose in the urine. The following table shows the results collected from the classroom data.

This shows that none of the participants were undiagnosed/untreated diabetics. This may be induced because no glucose was found in the urine. In diabetic, glucose would be present as the body is unable to use glucose, so it removes it from its system as it is unable to retain it.
