# 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.

Introduction

Anthony Crute Table 1 Concentration glucose g100cm�3 6 3.6 3 2.4 1.6 1.2 0.6 Time to decolourise manganese (VII) (s) 178 240 266 331 495 784 1180 Table 3 A B C D Start (m) 0.00 1.00 2.00 3.00 Finish (m) 10.00 9.00 16.00 N/A Time (m) 10 8.00 14.00 N/A Time (s) 600 480 840 N/A Table 4 Time to clear Glucose g.100 Actual divided by 10 Diabetic/ None Urine/ Blood plasma A 600 1.5 0.15 Diabetic Urine B 480 1.8 0.18 Diabetic Blood Plasma C 840 1.1 0.11 Normal Blood Plasma D N/A N/A N/A Normal Urine The actual shown in table 4 is found by dividing by 10 because the solution was concentrated 10 times so to find the actual figure it must be divided by 10. 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.

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.

1. ## Homeostatic Control of Blood Glucose Levels

4 star(s)

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.

3 star(s)

But bear in mind that a reduction in the insulin dose is often necessary as physical activity lowers the blood glucose, so the child should always carry sugar to avoid hypoglycaemic episodes (hypos). How is diabetes treated in children? Children with diabetes are always treated through insulin and diet management.

t distribution revealed that the likelihood of the difference between glucose and sucrose brewer's being due to chance was P<0.001. This means the probability that these results are due to chance is less than 0.001 or 0.1%, therefore more than 99.9% due to the manipulation of the independent variable, and are considered very highly significant.

1. ## Rate of Respiration

This will enable me to accurately record the volume of c02 produced, and using a large amount of respiration per each test ensures my results are reliable. I will then be able to plot this data to calculate the rate of respiration and observe any trends in the data.

Also they are susceptible to diseases which can make them need help to work or completely fail. But these diseases can be controlled or overcome with different methods and different medicines. Below are some of the diseases which can affect the kidneys.

Also the less the sugar there is the less respiration will occur because the raw material is limited. This explains the different results. Most of these explanations were listed in the prediction. My prediction that if the concentration doubles the mass lost will double wasn't proven to be correct apart
