Lab Group 3 Abstract This experiment shows the effect of rising temperature on enzyme amylase activity on converting starch to maltose. The reason for conducting the experiment is to find optimal temperature for enzyme activity. The enzymes that will be comparing are fungal and bacterial amylases. The enzymes were set at 4 temperatures 0-850 Celsius and checked at 4 different times

    When the enzyme amylase comes in contact with the starch molecules, it decreases the energy needed for the chemical reaction that breaks starch down into maltose, a simple sugar. The maltose molecules, or substrate. Fit perfectly into the enzyme’s active site, and thus the activation energy is reduced and the reaction can take place. This won’t work, however, if the enzyme is denatured. Denaturing occurs when either the temperature or pH of the enzyme is changed. In our lab, denaturing was simulated

    1938 Words  | 4 Pages

    Investigating Amylase Aim: The aim of the experiment is to investigate how effectively the enzyme amylase breaks down starch at different temperatures, and therefore to find the optimum temperature that amylase digests starch. Introduction: Thousands of chemical reactions take place in our cells and those reactions need to happen quickly in order to keep us active. These chemicals are called ENZYMES. Enzymes make reactions happen at a much faster rate. Enzymes come in two main

    2634 Words  | 6 Pages

    experiment “Digestion of Carbohydrates by Salivary Amylase” this dealt with a test where amylase was observed from a saliva sample and starch mix. Salivary amylase is a digestive enzyme that catalyzes the hydrolysis of starch of starch into simpler compounds (Saunders 1). The main function for salivary amylase is to break down starch. When it comes to starches, they are known to be complex carbohydrates. In order to see whether or not the amylase broke down the starch, you can add iodine to the saliva

  • Investigating the Rate of Reaction between Amylase and Starch

    1086 Words  | 3 Pages

    Investigating the Rate of Reaction between Amylase and Starch Plan Aim: The aim of this investigation is to find out whether the volume of amylase affects the rate of reaction between amylase and starch. Prediction: I predict that the greater the volume of amylase then the faster the rate of reaction between the starch and amylase will be. I predict this because of the lock and key hypothesis. The lock and key hypothesis explains how the substrate molecule (the starch) fits inside

    How Amylase Concentration Affects the Rate of the Starch Concentration In this piece of coursework, I have to carry out an investigation to find out how amylase concentration affects the rate of starch. Enzymes are biological catalysts that speed up the chemical reaction that goes on inside living things. An enzyme acts on substrate and may do its job inside or outside the cells. However, the rate at which enzymes work are affected by the following factors/variables: Concentration:

    Temperature for the Enzyme Amylase Aim: The aim for this experiment is to find out the best temperature for the enzyme amylase and at what temperature of water it works the fastest. I plan to collect evidence to prove that the enzyme amylase will work best at the temperature 37ËšC. I will choose a range of temperatures two below 37ËšC and two above 37ËšC so I will be able to determine what temperature it works best at. Prediction: I think that the enzyme amylase will work the best and

    Investigating How Quickly Amylase Breaks Down Starch With Varying Temperatures Instructions List I gathered the equipment shown below. I put 3 drops of iodine in each chamber of the spotting tile. I boiled the kettle and mixed together water from the kettle with water from the tap so the water reaches the correct temperature. The water was put into a beaker. 5ml of starch was put into a test tube. The test tube was placed into the beaker. When the water in the beaker was at the required

    A Biological Catalyst A Biological catalyst is a catalyst that is produced organically. In other words, a cell makes it. It is usually a protein or steroid molecule that works to catalyse a specific reaction. For example, amylase is a biological catalyst. Biological catalysts are called enzymes. Reactions take energy to get them started. This energy is called the activation energy. Enzymes catalyse reactions inside organisms. A catalyst is a molecule that acts

    In part A of the lab, our group measured the effects of emulsification on the digestion of lipids in the presence of cholic acid, a purified bile salt, and distilled water. The tube containing vegetable oil and no bile began to separate into two layers within the first minute of being mixed together. Although there were no clear distinctions within the first 15 seconds, by the fifth minute, there appeared two separate layers; one resulted in a yellow appearance while the other one was clear. As

  • Essay On Starch

    Starch is the predominant carbohydrates source in our diets. The digestion of starch in human starts in oral cavity and involves the enzyme amylase, it is produced by the salivary gland, and it is able to hydrolyze the alpha -1,4 glyosidic linkages in starch. (Tracey 2016) The presence of salivary amylase makes the process of digesting starch to occur in a much faster and efficient manner, since it does not have to wait till the food mixture to get into small intestine to start the breakdown of starch

    enzymes for this by not actually interfering with the reaction its self but basically align the two substrates on the active site of the enzyme. Amylases are widely spread enzymes that hydrolyse starch to maltose. They are often found in two forms, a-amylase, which degrades starch molecules into, fragments 10 glucose residues long and b-amylase, which breaks down these into maltose, made up of two glucose molecules. Both work by hydrolysis adding one molecule of water across glycosidic link

    another through glycosidic bonds. Amylase is a group of enzymes capable of digesting these glycosidic linkages by hydrolyzing, or splitting by addition of a water molecule, the starch into smaller carbohydrate molecules like glucose and maltose. It is best known for its function in beginning the chemical process of digestion in the human body, converting complex carbohydrates into forms usable in the body. However, with recent advances in biotechnology, the range of amylase applications has significantly
