Effect of temperature on amylase activity Rating:
Amylase is an enzyme that plays a crucial role in the digestion of carbohydrates. It is found in the saliva of mammals and is responsible for breaking down complex sugars into simpler sugars that can be easily absorbed by the body. The efficiency of amylase in carrying out this process is affected by a variety of factors, including temperature. In this essay, we will explore the effect of temperature on amylase activity and how this can impact the digestion of carbohydrates in the body.
At optimal temperatures, amylase exhibits maximum activity and can efficiently break down carbohydrates into simpler sugars. This optimal temperature range is different for different types of amylases and can vary from 37°C for human salivary amylase to 60°C for thermophilic amylases found in certain bacteria. As the temperature increases or decreases from the optimal range, the activity of amylase begins to decline.
At low temperatures, the movement of enzymes and their substrate molecules is slowed down, resulting in a decrease in the rate of the chemical reactions they catalyze. This is because the lower temperature causes the enzyme molecules to vibrate less, leading to a decrease in the frequency of collisions between the enzyme and substrate molecules. As a result, the rate of the chemical reactions catalyzed by the enzyme also decreases. In the case of amylase, low temperatures can result in a slower rate of carbohydrate digestion and a decrease in the efficiency of the enzyme.
On the other hand, high temperatures can denature enzymes, causing their protein structure to break down and lose their catalytic activity. This is because the higher temperature causes the enzyme molecules to vibrate more, leading to an increase in the frequency of collisions between the enzyme and substrate molecules. However, these collisions can cause the enzyme molecules to collide with each other, leading to the breaking of the weak bonds that hold the protein structure together. When this happens, the enzyme loses its catalytic activity and becomes inactive. In the case of amylase, high temperatures can cause the enzyme to denature and become inactive, leading to a decrease in the efficiency of carbohydrate digestion.
In conclusion, temperature plays a significant role in the activity of amylase and can impact the digestion of carbohydrates in the body. Optimal temperatures can lead to maximum enzyme activity and efficient carbohydrate digestion, while low or high temperatures can result in a decline in enzyme activity and a decrease in the efficiency of carbohydrate digestion. It is essential to maintain the optimal temperature range for amylase to ensure efficient digestion of carbohydrates in the body.
The Effect of Temperature on Amylase Activity
These enzymes have a secondary and tertiary structure and this could be affected by increases and decreases in temperature beyond the optimum temperature of the enzyme to work in. Therefore I wanted to examine the breakdown properties of a digestive enzyme while under the influence of a strong inhibitor. Alpha-amylase acts on malt starch to produce both fermentable and unfermentable sugars. It breaks starch down systematically to produce maltose. The bacterial enzyme activity showed clear temperature dependence from 0°C to 60°C. The tubes in the 80Ã? As a result, enzymes increase the rates of chemical reactions that are essential to live.
How temperature affects the rate of enzyme activity experiment? This implies that despite the fact that the chemical reactions of both the enzymes are lower at temperature zero, the rate of reaction of the bacterial amylase is slightly higher at that zero temperature compared to the chemical reactions catalysed by the fungal amylase. On the other hand, the fungal enzyme activity deteriorated more rapidly than that of the bacterial enzyme at higher temperatures of 40°C and 60°C. The eight test tubes were allowed to sit in their individual environments for ten minutes. Starch hydrolysis was maximal in the first 2minutes and remained plateau from 0°C to 60°C for the fungal enzyme, implying that the fungal enzyme operates rather efficiently at lower temperatures. Test the contents and record the results at intervals of 10 seconds. Word count-1453 Background research Enzymes are biological catalysts that speed up a chemical reactions. Start timing immediately the solutions are mixed.
Investigate the Effect of Temperature on Amylase Activity, Lab Report Example
How does temperature affect an experiment? Proteins are next tested. Test tube three was placed in a test tube rack at room temperature, approximately 22Ã? As a result, there was no start that was broken down at these temperatures. The change in color of the solution from blue-black to yellow signified the endpoint of the experiment. The rate of collision is higher than the one experienced at 20oC. It is prudent to note temperatures affects enzyme function by altering its shape which eventually changes its function because the substrate is not able to fit into the active site of the enzyme due to the altered shape.
Results should then be recorded at the end of the laboratory experiment. The function of amylase is to break down big molecules of starch The Effect Of Temperature On The Efficiency And Amount Of Activity Produced By Enzymes The Effect of Temperature on The Efficiency or Amount of Activity Produced by Enzymes Christopher Gonzalez-Riano Panther ID: 5439112 Lab Partners: Mariana Loys, Marc Pugliese, Alexis Delgado Abstract: All biological processes require a constant supply of energy. An increase in temperature typically increases the rate of reaction. They have active sites on which the substrate is attached, and then broken up or joined. Hypothesis As the reaction The Effect Of Temperature On The Enzyme Amylase And Its Activity When the experiment was conducted, the main objective was to determine how temperature affected the enzyme amylase and its activity.

Learn More Different conditions were provided for each test tube by placing them in water baths of different temperatures. The bacterial and fungal amylase did not react the way it was originally supposed to, causing there to be an error in our results. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision Figure. Half of the laboratory experiment did not indicate any change of color. Larger carbohydrate molecules are broken down into smaller molecules through hydrolysis reactions. The increased rate of collision between the amylase and substrate results to more starch binding to the active sites of the enzyme amylase hence increasing the rate of digestion.
When an enzyme is within its Optimal Range or conditions, it will be able to catalyze reactions at its fastest rate. Starch turns to a blue-black color when comes in to contact with iodine solution and the addition of amylase speeds up the breakdown of starch such that the blue-black color does not appear when iodine solution is added indicating that the mixture has not starch compound. The wells turned blue-black when the starch was added to the iodine. Heating above this temperature begins to destroy the amylase. Experiment Evaluation The test tubes were left in the water bath for 5 minutes to allow the temperature of the solution and that of the water bath to equalize to improve the reliability and accuracy of the results.
Effect of Temperature on Amylase activity (Enzymology Protocol)
Moreover, enzyme reaction rates are influenced by different factors such as temperatures, pH, and even stress in the human body. General Biology Laboratory Bio III. An Iodine test was carried out to observe the starch hydrolysis process. The color was a 4 at 2 and 4 minutes while it was a 3. Amylase increases the rate of reaction by decreasing the activation energy needed to hydrolyse the starch molecules. Record and keep your results securely. Variables Dependent variables: the required time for the disappearance of blue-black color color of Iodine solution mix with starch solution.
Study the Effect of Temperature on Salivary Amylase Activity
The first characteristic of an enzyme is to increase inside the human body depending on the rate of reaction. However, starch from food contains chained monosaccharides that have to be broken down to allow for absorption of the food into the body cells. The conversion of starch by a-Amylase increases in rate with rising temperature to a maximum of about 80oC. Add 1 cm3 buffer solution into each of the above test tubes. . A test plate was obtained, and several rows of the test plate were filled with one or two drops of I2KI iodine-potassium-iodide. This was recorded the absorbance every 20 seconds for 3 minutes.
