Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1. Like all enzymes‚ amylase must be kept

There are a lot of activities to enjoy around us. We are able to divide two type of activities such as indoor activities and outdoor activities. Some people like outdoor activities such as a baseball‚ football. Others like indoor activities such as volleyball‚ table tennis. In case of indoor activities‚ regardless of weather‚ people want to play sports‚ they can enjoy them. However‚ I prefer playing outdoor activities. There are two reasons why I think so. First‚ outdoor activities help people to be

The sprint activity can be influenced by many anatomical‚ physiological‚ and morphological factors. These factors will be explained in this paper to identify the normal and abnormal status which may affect the sprint performance when analyzing the sprinting activity: • Stride length: Optimal sprint stride length can be achieved when the sprint is performed in proper technique. Stride length is defined as the distance covered with each stride and is improved by increasing the amount of force applied

The Eo’ value for this indicator is 0.53V. (n = 2) What is the useful voltage range of this indicator? (B) Starch indicators are useful when iodine titrations (organic oxidations) are performed. Why is it considered an advantage in these titrations to have iodine as the titrant instead of the analyte? 3. An environmental chemist is going to field test the chemical oxygen demand factor for a stream in Yellowstone Park.

Test for the Presence of Macromolecules Introduction In this experiment‚ we are trying to identify the presence of macromolecules in certain solutions. As in our daily lives‚ macromolecules are the essential nutrients that we have to take every day‚ therefore we would like to identify the types of macromolecules that contain in some of the food or solution in order to maintain a healthy life. There are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and

Using the Iodine clock method to find the order of a reaction Introduction When peroxodisulfate (VI) ions and iodide ions react together in solution they form sulfate (VI) ions and iodide. This reaction is shown below: S2O82-aq+ 2I-aq SO42-aq+ I2(aq) The reactants and the sulfate (VI) ions are colourless however the Iodine is a yellow/brown colour. This allows you to measure the progress of the reaction through the colour change when the iodine is produced. In order to determine the order of

techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate reduction‚ etc. Biochemical testing is very important in

Anxiety can a hit a person at any moment. For many‚ test taking is the most difficult task there is. Profuse sweating‚ fast heart rate‚ and nausea are minor symptoms a person can become overwhelmed with while taking a test. More than likely‚ this person has experienced test anxiety. Test anxiety is a psychological condition in which people experience extreme distress and anxiety in testing situations (Cherry‚ 2015). When it comes to test anxiety there are physical‚ emotional‚ and behavioral symptoms
