fungus amylase and also discovers the optimum temperature for these enzymes. The amylase was mixed with starch at temperatures of 0℃‚ 37℃‚ 57℃‚ and 90℃. Iodine was added to each mixture and colour changes in each case. Bacteria amylase was found to be effective at 55 0C as the temperature dropped drastically from 4.58℃ to 2.33℃. This shows that the amylase catabolized a lot of starch hence little is left which cannot turn the iodine solution to blue-black which indicates the presence of starch. Fungal

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

This study focuses on the effect that temperature has on the enzyme amylase. Enzymes are composed of proteins and acts as a catalyst to speed up the rate of a specific chemical reaction by lowering the activation energy. Reactions do not need enzymes to occur‚ but the human body and other living organisms depend on the use of enzymes in order for biochemical reactions to happen in milliseconds. Each enzyme contains a distinct three dimensional structure which is related to its particular function

Temperature and PH of Barley Amylase Abstract The purpose of this experiment was to find the optimal temperature and pH of barley alpha-amylase. I hypothesize that the optimal temperature would be 55 degrees Celsius and the optimal pH would be 5.5. In this experiment‚ the starch is used as a substrate to examine the optimum temperature and pH for the reaction of alpha amylase. It is known that the measuring of disappearance (absorbance) of the substrate starch with iodine using spectrophotometer

Experimental Analysis on Enzymatic Behavior of Human and Fungal Amylase Lab name and number: Enzymes‚ Lab #5 Panther I.D: 2640403 Shayra Medal Instructor: Emily Nodine Section U21 October 26‚ 2011 X_______________________ Abstract Section The concept of this experiment was to analyze the enzyme Amylase and its environmental behavior. Amylase breaks down the biological macromolecule‚ carbohydrates‚ specifically starch into condensed subunits categorized as monosaccharaides or disaccharides

reaction. Each enzyme binds closely to the substrate; this greatly increases the reaction rate of the bounded substrate. Amylase enzyme‚ just like any other enzyme‚ has an optimum PH and temperature range in which it is most active‚ and in which the substrate binds most easily. The purpose of this experiment was to determine (1) the reaction rate of an amylase enzyme in starch and (2) the environmental factors that can affect the enzymatic activity. The hypothesis‚ in relation to the enzymatic

is 53 Celsius. Extremes in the temperature and the pH of an enzyme can denature therefore destroy it. The enzyme that is in this experiment is Amylase. Amylase is found in germinating seeds. These seeds contain starch in their endosperm. With the help of Amylase enzyme‚ the starch (Amylose) is broken down to Maltose. Amylose contains about 20 percent starch and is more water soluble‚ therefore it is hydrophilic.

Amylase And Its Functionality At Various Ph Level Abstract Enzymes can be denatured at various ph levels in which then affects the shape of the enzymes structure and reactivity. The altering of shape causes substrates to not bind in the active site (Scott Freeman‚ Micheal Harrington‚ Joan. C Sharp‚ 2009). Amylase is used as a catalytic enzyme to determine the time period to convert starch into glucose monomers and transport into the bloodstream at different ph levels
