I can tell by referring to my tables that solution A is a Diabetic and the sample is urine, I can tell this because the biuret test which is shown in table 4 showed it was urine and the fact that there is any glucose in it proves the person is diabetic. ...read more.

Middle

The Biuret test used in table 4 works in this way, a purple colour indicates the presence of protein. A blue colour is a negative result showing no protein. It works because sodium hydroxide breaks a protein into short peptides and the peptide bonds form coloured compounds with copper (II) ions in the copper sulphate. There are certain levels used to establish whether a person is diabetic or not after using tests which measure glucose amount in blood and urine. These are the sorts of results shown in table 4. In diabetic urine there is some glucose. In normal urine there isn't any glucose. In diabetic blood plasma the glucose level is more than 0.12 100cm�3 In normal blood plasma the glucose level is between 0.08g and 0.12g 100cm�3 No glucose should be in the urine of a none diabetic, this is because in a non-diabetic the glucose is reabsorbed in the kidneys stopping it getting into the urine whilst in a diabetic it is passed into the urine the results of this can also bee seen in the tables. ...read more.

Conclusion

The destruction of the beta cells is an autoimmune response. The uptake of glucose by brain cells and red blood cells is not dependant on the presence of insulin, but even in the presence of abundant glucose the sugar is not taken up by the muscles in the absence of insulin. Non-insulin dependant (type 2) diabetes occurs when the body does not produce enough insulin and that which is produced becomes less effective on the target cells. This type of diabetes can usually be controlled by diet, but sometimes insulin injections are needed, glucose is needed in the body to be broken down into ATP which provides energy to the body, which the body needs to survive so when the glucose is not properly taken up the human body would die, this explains my other results which are that of diabetics. I studied the table and discovered that most of my results are not within standard deviation, the ones outside the standard deviation are 3, 2.4, 1.2, 0.6. 3 is 4 over the standard deviation, 2.4 is 12 over the standard deviation, 1.2 is 96 over the standard deviation and 0.6 is 38 over the standard deviation so overall my results are not reliable. ...read more.

    The corresponding effect of this antagonistic mechanism occurs when blood glucose level have fallen too low - this is detected in the Islets of Langerhans by the alpha cells which are stimulated to produce glucagon. This hormone acts in two main ways to raise blood glucose concentration back to normal levels.

    My results have been backed with my original theories. Evaluation I feel my plan did succeed as I managed to predict the results with a reasonable degree of accuracy and also gave good detailed theories supporting my prediction. I also feel that I've constructed the method so that it is easy to understand and easy to carry out the investigation.
