Biology Action Of Amylase Enzyme On Starch

672 words - 3 pages

AimWe are trying to find out how the action of amylase enzyme on starch is influenced by temperature.PredictionMy prediction is that the lower the temperature the longer it will take for the two substances to turn a pure yellow indicating the starch has been converted into sugars (glucose).Scientific reasonParts of the digestive system produce enzymes which speed up the digestion of food. When the food has been digested it is absorbed through the wall of the intestine. The small soluble molecules pass through the wall into the blood vessels surrounding the intestine. The blood vessels around the intestine are the starting point of a journey for the food molecules. From there they are carried to wherever they are needed. The breakdown of the large food molecules is speeded up by enzymes. Enzymes are made by special tissues along the length of the gut. As the food passes along the gut, the enzymes pour onto the food. Carbohydrases catalyse the breakdown of starch into sugars. Carbohydrases is made in the pancreas, small intestine and the salivary glands. The salivary glands produce saliva which contains the enzyme salivary amylase. The enzyme is a carbohydrase which begins the breakdown of starch to sugar.Amylase is also used for washing dishes. The dishwasher powders remove starch smears on platesEquipmentTest tube rack, three test tubes, beaker of amylase enzymes, beaker of starch, small syringe, large syringe, pipette, iodine, stop clock, white tile, Bunsen burner, water bath, thermometerFair testWe will make it a fair test by changing some things and keeping other things the same. We will add the same amount of iodine each time otherwise it will affect the test. We repeat the test twice to check our results and we will keep the same amount of both substances.MethodFirst we measure 12 ml of starch in a syringe and put it into one test tube. We then measured 1 ml of amylase enzyme and put it into the second test tube. These test tubes were placed into the test tube rack. These two liquids were then...

The Effect of pH on the Activity of the Enzyme Amylase

1658 words - 7 pages The Effect of pH on the Activity of the Enzyme Amylase Aim :- To find the effect of pH on the activity of the enzyme amylase. An enzyme is a type of protein found in all living cells. Enzymes act as biological catalysts, breaking down substrates without needing a high temperature, allowing all the chemical reactions of metabolism to take place, regulating the speed at which they progress, lowering the activation

1496 words - 6 pages The effect of Lead ions on amylase activityAimWhat is the effect of Lead ions on the enzyme Amylase. And does it have an inhibitory effect, which causes the substrate, in this case starch to be blocked from the reaction process in the enzyme catalyst. Also is the effect reversible or irreversible, which is put on the amylase.MethodApparatus and substances requiredTest tube holder 2% starch solution6 boiling tubes labelled 1 to 6 1% lead nitrate

Biology: Experiment- The Effect of Temperature on the Enzyme Rennin

1890 words - 8 pages Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin.Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC, which is the body temperature, where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the

The effect of concentration of enzyme and enzyme substrate on the rate of an Enzyme-catalysed reaction

3271 words - 13 pages decrease due to denaturation of the enzyme.I would expect from this reaction as the concentration of the enzyme catalase is increased that the amount of oxygen produced would increase, too. This is because catalase speeds up the decomposition of hydrogen peroxide into water and oxygen. Catalase exerts the effect on chemical reactions by providing a place for the hydrogen peroxide, the substrate, to interact. So as the concentration of catalase increases

Group three pondered this lab's inhibitor, phenylthiourea (PTU).Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it, and thus "wins" the position at

Hydrogen peroxide is highly reactive and forms during metabolic reactions that require oxygen. It can also form oxygen radicals that oxidize organic molecules and are potentially quite harmful. The enzyme catalase is able to neutralize hydrogen peroxide and protects the molecules that are important for life. Catalase is an example of an anti-oxidant, aptly named
