To investigate the effect of temperature on an enzyme controlled reaction
Introduction and planning
For the investigation of enzymes, I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch.
The enzyme that we are going t...
Enzymes lower the activation energy of chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH's. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction.
Investigate the effect of temperature on amylase activity
Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants, animals and microorganisms. Large amounts of amylase occur in germinating cereals, and in the pancreas and...
The researcher is conducting this experiment to find the optimum temperature and pH for starch on amylase. The experiment was carried out in one day. The researcher and a partner did the experiment based on a lab manuel from class. Data was collected from the experiment and to be displayed...

This study of the effect of temperature on the enzyme amylase was performed to determine the correlation between the two. The experiment was developed to test the enzymes reaction rate of amylase digesting starch at several different temperatures and see how the rate changed. The...
The effect temperature has on the activity of the enzyme α- amylase.
Enzymes are a biological catalysts, which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all...
Enzymes are proteins that lower the activation energy needed for chemical reactions. The two main environmental factors that can affect the enzyme’s activity are temperature and pH, and each enzyme works best at a particular temperature and pH. The purpose of this enzyme kinetic expe...

AIM: To investigate the effect of substrate concentration on the enzyme amylase
Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as a...
Effect of varying Temperatures on Enzymatic Activity of Bacterial and Fungal Amylase and hydrolysis of Starch
This experiment consisted of setting up a control group of starch in various temperature and then placing both fungal amylases and bacterial amylases in a mixture of starch an...
Correlation between the chemical activity of Amylase and change in temperature
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 co...
Enzymes and Temperature
Purpose (Objectives): The purpose of this experiment was for students to be able to understand the enzyme-facilitated reaction and explain how enzyme activity can be affected by environment conditions....
DIFFUSION AND THE EFFECT OF AMYLASE.
We will interpret and explain the activity of an enzyme added to a solution. We will analyze reactions in different pH ranges.
The starch solution will appear blue when mixed with iodine. But after mixing the e...
Effects of Temperature and pH on Enzyme Function
Robin Cotter Introduction
The purpose of this experiment is to identify three unknown enzymes. This is done by
using different temperature and pH to affect the function of the enzyme, which ultimately, will
Enzymes are the catalysts of biochemical reactions that are produced in the cell. It changes the rate of reaction but is not consumed by it. The reaction produced breaks up substrate molecules, and afterwarc, the enzyme is free to move on to another substrate molecule. The substrate...
Factors Affecting the Rate of Enzyme Activity
Malt amylase (enzyme) was tested in different enzyme concentration, substrate concentration and environmental factors such as pH level, temperature and inhibitor (ZnCl2) in order to see the effect of those factors to the ability of enzyme breaking dow...

The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme, and how the enzyme works is competed by a compet...
Enzymatic Activity of Salivary Amylase
Abstract: Salivary amylase is an enzyme that can digest starch molecules and break them down to sugar molecules. In this experiment, the enzymatic activity and specificity of salivary amylase was examined depending on the changes in pH and temperature. In the...
