iodine solution is added and flushed. The higher the amylase activity‚ the more the starch will be broken down. Hence‚ a larger and clearer zone will be observed. Thus the diameter of the clear zone can show the activity of the amylase. In this experiment‚ the independent variable is the types of washing powder in the solution. The dependent variable is the diameter of clear zone on agar plate. The controlled variables are the concentration and volume of washing powder solution added into well‚ size

Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are

it’s lowest to do so. However‚ in cold solutions the starch will take longer as it will in temperatures beyond 40 degrees. Once it reaches this point‚ the break down will either take a very long period of time or have no reaction at all as enzymes are denatured at a certain point.

Biology “Enzyme Activities” Introduction: Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces. At the most basic level‚ a cell is really a little bag full of chemical reactions that are made possible by enzymes (Brain). Laboratory

milk Introduction Enzymes are globular protein‚ responsible for most of the chemical activities of living organisms. They are made up of long chains of amino acids containing carbon‚ hydrogen‚ oxygen and nitrogen (Gunsch‚ 2012). The role of enzyme is to act as catalysts‚ substances that speed up chemical reactions without being chemically altered during the process. The speeding up of chemical reactions is done by lowering the activation energy required to start a reaction. Enzymes are specific in

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

effect of pH on amylase activity Aim The aim of the experiment is to determine the effects of different pH and the rate of reaction on fungal amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies normal
