3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without the surface of the enzyme present. Enzymes achieve this by lowering the

Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present

Abstract In this lab‚ we tested the effects of temperature on fungal amylase and bacterial amylase (Aspergillus oryzae and Bascillus Licheniformis). We used 4 different temperatures in Celsius 0‚ 23‚ 58‚ and 89 for both fungal and amylase. For 10 minutes‚ every 2 minutes we would use 3 drops of each amylase and mix it with iodine to observe the presence of starch at each temperature. We conducted this experiment for both bacterial and fungal amylase. Results were reached based on the color of the

What is Enzyme? Enzymes are protein that acts as speed up reactions and break down molecules in our body. However‚ different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times.(3) In our human body‚ there are a total about forty thousand types of enzymes and each catalyzes different kind of molecule.(3) The molecules that enzymes help to accelerate is called substrates‚ and when enzyme is combined together with the substrate‚ it

The Effects of Temperature on the Action of Diastase on a Starch Suspension Hypothesis: The practical being carried out is to observe the effects of temperature on starch break down using a synthesized version of salivary amylase‚ this being Diastase. The starch will be placed into the Diastase and water and then placed in baths of water of different l. temperatures. The test tube containing water will have little or no reaction at all. However‚ the test tube containing the Diastase

project is to demonstrate how water temperature affects the dissolving of sugar in liquid. Everything in our universe is made up of particles which are in constant motion. In a solid state particles move the slowest while in a liquid state particles move the fastest. Under the right conditions‚ solid particles (the solute) when mixed in liquid (the solvent) can form a solution. This occurrence is called dissolving. I wanted to answer the question; does the temperature of water affect the speed at which

17th‚ October 2010 Margarita SA: VOL RATIO AND AGAR BLOCKS Conclusion: For this experiment the agar jelly had to be cut in to five different block sizes‚ after that has been done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the

The effect of different temperature on the cell respiration. Introduction： Cell respiration is the controlled release of energy from organic compounds in cells to form ATP‚and then release waste products. The process of cell respiration can take place in the presence or absence of oxygen. In either case‚the first stage of cell respiration is glycolysis.The effect of temperature on cell respiration mainly depends on the effect of temperature on of enzyme activity.Generally speaking in a certain

pH Affecting on Amylase Enzyme Is there a difference in the concentration of pH in the amylase enzyme activity? The null hypothesis would be that there will be no difference in the concentration of pH and alternative hypothesis would be that there will be a difference in the concentration of pH. The predication if that there will be a difference in the concentration of pH. The pH affects on enzyme activities‚ one of the enzyme that was used in the process was amylase. When a serial dilution was

SCH4U 03/04/13 Hydrogen Bonding Purpose: The purpose of this investigation is to test the concept of hydrogen bonding. Hypothesis: Given the concept of hydrogen bonding I predict that the bulky glycerol molecules limits the number of possible hydrogen bonds. If water is mixed with glycerol should make it possible for water to form many hydrogen bonds with the glycerol molecules‚ causing it to become a exothermic reaction. Because glycerol has more possibilities for hydrogen bonding I believe
