A Study of Enzyme Alpha Amylase (1280 words, 3 pages)

ABSTRACT The enzyme alpha-amylase is a catalyst to break up starch to from glucose. Without being consumed in the reaction, enzymes are catalysts that speed up the rate of the reaction. They achieve this by combining with a substrate and then separating from it form products. Environment factors that affect ... Read More

An Introduction to the Analysis of the Enzyme Catalase (579 words, 2 pages)

To investigate the factors that affects the reactivity of the enzyme Catalase. Catalase is an enzyme, which is present in potatos it breaks down Hydrogen peroxide in to Water and Oxygen. Enzymes are biological catalysts. An enzyme is protein that acts as a catalyst in biochemical reactions. Each enzyme is ... Read More

An Introduction to the Analysis of Enzyme (552 words, 1 pages)

An enzyme is a catalyst, which is a chemical agent that changes the rate of a reaction without being consumed by the reaction. The reactant that an enzyme acts on is called its substrate. While the enzyme is bound to the substrate, the catalytic action converts the substrate to the ... Read More

An Analysis of the Topic of the Identification of an Unknown Plasmid and the Restriction Enzyme Interaction (1746 words, 3 pages)

DNA and Restriction Enzyme Interaction Identification Of An Unknown Plasmid Abstract The fundamental purpose of these experiments is to research the interaction between DNA molecules and restriction enzymes. Two different experiments are performed. In the first experiment, two restriction enzymes, Hind III and Bam H1 interact with an unknown plasmid ... Read More

An Overview of Enzymes (4386 words, 14 pages)

Biology (HSC Course) Topic 1 Maintaining a Balance Enzymes The Role of Enzymes Enzymes role is to maintain the rate of chemical activity in an organism. They are biological catalysts, increasing the rate of reaction in metabolic processes. They also enable reactions to occur at lower temperatures, which means that ... Read More

The Types of Enzymes and Their Use in the Industry (2371 words, 4 pages)

Enzymes In this essay, the different types of enzymes existing are going to be discussed and how they are used in industry is also going to be discussed. There are 2000 different enzymes existing in the world. These enzymes are grouped according to the type of reaction they catalyze, (speed ... Read More

An Introduction to the Analysis of an Enzyme (2841 words, 5 pages)

Planning. Introduction An Enzyme is any one of many specialised organic substances, composed of polymers of amino acids, that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms. Those enzymes identified now number more than 700. Enzymes are classified into ... Read More

The Characteristics of Catalase, an Enzyme (1040 words, 2 pages)

What is Catalase? Enzymes are very large and complex organic molecules that are synthesized by the cell to perform very specific functions. These biological catalysts are important because they speed up the rate of the reaction they catalyze that would otherwise be too slow to support life. Catalase is an ... Read More

Effects of Glucose-6-Phosphate (G6P) on the kinetics of the Enzyme Alkaline Phosphatase (2164 words, 6 pages)

Glucose-6-Phosphate Appears to be a Competitive Inhibitor of the Bovine Intestine Enzyme Alkaline Phosphatase Abstract This study focuses on the effects of glucose-6-phosphate (G6P) on the kinetics of the enzyme alkaline phosphatase. Because G6P is a common molecule and has a phosphoester bond, it may prevent alkaline phosphatase from hydrolyzing ... Read More

An Investigation of Enzyme Activity Through Testing for Changes in Starch Solution with the Addition of Enzyme Amylase (728 words, 2 pages)

Enzyme Activity Aim To investigate enzyme activity by testing for changes in a starch solution when the enzyme amylase is added and how this reaction is affected by heat, pH, ratios etc. Background of Enzymes Enzymes are biological catalysts produced by living cells. Like all catalysts, they greatly speed up ... Read More

A Chemical Experiment Involving the Catalase Enzyme and Hydrogen Peroxide (2524 words, 9 pages)

Hypothesis Enzymes such as Catalase are large protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. They are all specific as each enzyme just performs one particular reaction. In their globular structure, one or more polypeptide chains twist and fold, ... Read More

An Experiment That Examines How the Concentration of the Substrate Hydrogen Peroxide Affects the Enzyme Catalase (2863 words, 5 pages)

INTRODUCTION The enzyme catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown here, 2H2O2-------------------2H2OO2. It is one of the fastest known enzymes and its turnover number is 6 million, which means the number of substrate molecules which one molecule of the enzyme turns to products ... Read More

Enzyme Action: Testing Catalase Activity (1224 words, 3 pages)

Enzyme Action Testing Catalase Activity Introduction Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic ...

An Investigation into How the Concentration of Substrate Will Affect the Rate of an Enzyme Controlled Reaction (3605 words, 8 pages)

An Investigation into how the Concentration of Substrate will affect the Rate of an Enzyme Controlled Reaction Introduction I am going to investigate how the concentration of hydrogen peroxide affects the rate of reaction between the hydrogen peroxide, and its enzyme, catalase, which is found in yeast. There are many ... Read More

Importance and Benefits of Enzymes In The Human Body (959 words, 2 pages)

Amylase Starch Maltose I2KI starch Benedicts sugar Like most chemical reactions, the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree Centigrade rise in temperature will increase the activity of most enzymes by 50 to 100. Variations in reaction temperature as small as 1 or ... Read More

Measuring the Absorbance of Enzyme Activity (636 words, 2 pages)

The purpose of this experiment was to measure absorbance of enzymes activity at different times. The experiments simplified by using substrate as a phenolphthalein monophosphate (PMP) (Shown in fig.1). Phenolpthalein was pH indicator it appeared colourless below pH 9 then turned pink above pH 10. In this experiment alkaline phosphatase ... Read More
