(Effect of concentration on enzyme activity)
An Enzyme is a protein, which is capable of starting a chemical reaction, which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an
Experiment 4 – Effect of Temperature on Enzyme Activity
To study the effects of temperature on the activity of amylase enzyme on starch solution.
Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually
Investigating the Effect of Temperature on Enzyme Activity
Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation, you will design an experiment to determine the effect of
Effect of temperature on enzyme activity
In this experiment…
Independent variable: Temperature of the amylase
Dependent variable: Enzyme activity which is measured by the time for disappearance of starch
Controlled variables: Volume of amylase; volume of starch solution; concentration of amyla

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
Title: Enzyme Activity Lab
Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors, such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature, that affect enzyme activity.
Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A, B, C, and D. In activity A, the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction, to study the...
THE EFFECT OF TEMPERATURE ON CATALASE
What is the effect of various temperatures, 0°C, room temperature, 37°C, 50°C, 60°C, on the number of oxygen gas bubbles liberated, in a decomposition reaction between the enzyme Catalase, obtained from crushed mung beans, and 2%...
How does temperature affect enzyme activity?
In this practical investigation, my aim is to discover how temperature will affect enzyme activity, by looking at the rate of reaction.
I predict that the higher the temperature will be, the faster the reactions take place....
Starch is composed of α-amylose and amylopectin. The structure of α-amylose consists of long polymer chains of glucose units connected by an α (1-4) linkage. Amylopectin consists mainly of α (1-4) linked glucose residues but is a branched molecule with α (1-6) branch points ever
Temperature Affecting Enzyme Activity
The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life's processes would not come so easily. Enzymes are basically proteins, which have specific shapes for different substrates. Enzymes chan
The purpose of this lab was to measure the extent of enzyme reaction on given substrates by means of color change. The reaction followed is given below:
