effect of the temperature on the action of an enzyme Abstract The experiment was to analyse what reaction temperature would have on Amylase enzyme. We heated alpha amylase solution to set temperatures then tested for the presents starch with iodine solution. Any starch would turn the iodine black. Once the starch had broken down the iodine would remain brown to suggest the presents of maltose. Usually I would expect to find that the reactions would increase as the temperature increased. After

Paper: Effect of Water Temperature on Amylase Using Colorimetric Starch Assay Introduction For plants to function properly, chemical reactions must take place within the cells of each individual plant. Energy is necessary for each reaction to occur. The amount of energy that is necessary for a reaction is called the activation energy. Enzymes are used to reach the correct activation energy in plants. They lower the activation energy to the correct amount for the reaction to take place. Certain

Introduction: Photosynthesis is one of the most fundamental processes that take place in plants and some other organisms. Photosynthesis converts solar energy into chemical energy of a carbohydrate (Mader & Windelspecht, 2013).The whole process takes place in the chloroplasts of green plant cells containing the pigment chlorophyll. Chlorophyll is one of the most important molecules in existence as all energy capture starts from there (Mader, 2010). If none of this pigment is in existence, plants

Introduction. This is an experiment to investigate into the rate of reaction between sodium thiosulfate (Na2S2O3) and dilute hydrochloric acid (HCl). The formula for this reaction is: Na2S2O3 (aq) + 2HCl (aq) 2NaCl (aq) + S(s) + SO2 (g) + H2O (l). This makes the products Sodium Chloride, Sulphur Dioxide, Sulphur and water Rate of reaction is the speed at which a chemical reaction takes place. Some reaction can take less than a second and other can take over millions of years. During

After it was first discovered in 1886 by Hans Heinrich Landolt, the iodine clock reaction has become one of the most used classroom experiments for demonstrating kinetics (SuperchargedScience, 2018). A clock reaction is a reaction where one of the chemical species (clock chemical) starts off with a low concentration and then has a rapid increase which can then lead to a dramatic colour change (UnitverityNottingham, 1999). The iodine clock works by using iodine as the clock chemical that then reacts

effects of enzymes, many crucial chemical reactions would not be able to take place at the rate of which they were meant to perform. We conducted this series of labs in order to discover the effects of different biological and environmental aspects on enzymatic activity. In our first experiment, we looked at the effects that enzyme concentration had on amylase activity. We hypothesized that the higher the concentration of the enzyme, the higher the rate of reaction would take place. We found that a

al., 1998). It catalyzes the conversion of a large number of catechols producing a dark pigment called melanin, which is the product of the chemical reaction. Studies on enzyme activity are important in order to establish some controls. In particular, with regards to the cathecol oxidase, its inhibition can help to reduce the pigment production and the darkness of some vegetables and fruits. This is obviously

Hillsborough Community College - Ybor City Campus 1025C Laboratory Exercise 3: Characteristics of Enzymes Introduction What are Enzymes? Enzymes are very large and complex proteins that that function as catalysts. They are synthesized by the cell to perform very specific functions. Each type of enzyme has a very specific shape (conformation) which provides its specific function. The shape of an enzyme molecule is determined and maintained by many weak intermolecular interactions between many different
