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.

2. ## What is Type 1 diabetes

3 star(s)

Physical activity also plays a role in how much the child can eat. Before the child participates in sporting events, it is, therefore, recommended to give some extra bread or juice and other carbohydrates. Three main meals and two to three snacks, where the whole family eats the same, are recommended.

1. ## The comparison of antibacterial properties of herbal products and standard antibiotics

5 star(s)

This could explain why some of the results were irregular and this could also be due to the fact that technique lacked when spreading the bacteria and at least twice the agar jelly was damaged. Taken into account is that it is obvious the results are going to vary slightly as the concentrations are different.

2. ## &amp;quot;An investigation into the Respiration of Carbohydrate Substrates by Yeast.&amp;quot;

5 star(s)

This means the probability that these results are due to chance is more than 0.05 or 5%, therefore less than 95% due to the manipulation of the independent variable, and are not considered significant.

If the temperature is changed, for example, too high then this may denature the enzymes used by yeast to digest substrates. pH I will control the pH by adding the substrate to a buffer solution A change in pH may damage the enzymes the yeast may use to digest the substrate (such as maltase)

The liquid filtrate is then collected at the pelvis destined for removal from the body. vii. Bladder: Two ureters track down the back of the abdomen and feed into the bladder. An average bladder can normally hold about half a pint of urine before the brain tells the person they need to excrete it.

potato tissue will take in water through osmosis until the two solutions are of equal concentration. Therefore the water will diffuse by osmosis into the potato from an area of high concentration down the concentration gradient. This will result in a gain of mass for the potato.

2. ## Diabetes Mellitus

* Glucagon increases the liver's ability to make glucose from other compounds, such as amino acids. As with insulin, the most important factor that controls the release of glucagon from the pancreas is the blood glucose level. As blood glucose rises, glucagon output falls and vice versa.
