Investigating the Optimum pH Bacterial and Mammalian Amylase Digests Starch Solution [IMAGE] Biology Coursework Monique Noel 12T Finding the Optimum pH Bacterial and Mammalian Amylase Digests Starch Solution. Introduction I am investigating the optimum pH bacterial and mammalian amylase digests starch solution. To do this I will conduct an experiment using bacterial and mammalian amylase, subjecting them to varying pH levels and record at which pH level the enzyme
and bacterial amylases are the two enzymes tested in this experiment to see their ability to break down starch. To determine how temperature affects
Effect of Lead Ions On Bacterial and Fungal Amylase Amylases are enzymes, which hydrolyse starch into Maltose. There are two types of amylase: Alpha amylase that degrades starch, which is a polysaccharide, into fragments 10 glucose residues long. Beta Amylase breaks these down into maltose, which is a disaccharide of two glucose molecules joined together. Both enzymes work by hydrolysis of the glycosidic link in carbohydrates. Enzyme amylase are produced from different sources but
4007353 Juan, Victoria, Lilly, Tiffany Chung The effect of varying temperature on amylase converting starch to maltose. 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

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
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
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
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:
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
The Effects of Enzyme Concentration on the Activity of Amylase To investigate the effect of Amylase concentration on its activity. the relative activity of Amylase is found by noting the time taken for the starch substrate to be broken down, that is, when it is no longer gives a blue-black colour when tested with iodine solution. This time is referred to as the achromatic point. Equipment: v Amylase solution 0.1% v Starch Solution 1.0% v Distilled water v Iodine in potassium
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
Rennin – A Proteolytic Enzyme Major Discussion: Role of rennin in helping young mammals digest milk Role of rennin as an industrial catalyst to make cheese Proteolytic Enzyme: Any group enzymes that catalyze the hydrolytic degradation of proteins or polypeptides to smaller amino acids polymer is called proteolytic enzyme. Rennin is a proteolytic enzyme made by chief cells in the stomach. Rennin also known as “Chymosin”. Rennin enzyme plays an important role in helping young mammal digest milk
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
enzyme amylase from digestion system, which it has a big part in breaking down carbs into maltose, glucose and others. And our data by end of the lab could lead us to the specific conditions which are required for amylase in order to do its job perfectly. Hypothesis: Carbohydrates: Starch + Amylase: amylase duty is to digest starch by catalyzing hydrolysis, which lead the starch to form into Maltose, which is around the same size as two joined glucose molecule, so base on this If we mix amylase by
Investigating the Effect of Copper Sulphate on Amylase Activity Aim The aim of my experiment is to observe the affect on amylase when adding copper sulphate to a starch solution. Introduction Enzymes are that act as catalysts, in other words they increase the rate of chemical reactions. Consider the following general reaction between two substances, A and B, which react together to form a product, substance C: A + B = C In biological systems, this reaction might occur very
Investigation to Determine the Effect of Temperature on the Activity of the Enzyme Amylase I am trying to find out if changing temperatures affects the activity of enzymes. The Input variable I will test is temperature; the range I will use for this is 0-80°C. The out come variable to be measured is the speed of the reaction. Hypothesis I believe that at a higher temperature the enzyme will react quicker, but at a certain temperature the enzyme it will stop working
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
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
