An investigation into the effect of a germination inhibitor on the germination of seeds

For a seed to germinate there are specific conditions different seeds need. In this experiment, cress seeds are to be used. Going through the basics first though, for a seed to successfully germinate there needs to be:o An adequate supply of watero A suitable temperatureo An appropriate partial pressure of oxygeno A suitable supply of […]

Enzyme concentration and enzyme activity

For this investigation, we are going to find out how different enzymes (in this case, trypsin) concentration in a solution would affect the rate of which solute (Casein) is broken down. I think enzyme concentration would definitely have an effect on the rate of reaction. My hypothesis is that increasing the concentration of trypsin would […]

The uses of enzyme in industry

Any group of chemical substances which are produced by living cells and which cause particular chemical reactions to happen while not being changed themselves (Cambridge Advanced Learner’s Dictionary) ffffAlso with the ability to catalyze certain reactions, make enzymes a very suitable in the making of specific products. Enzymes do this by lowering the activation level […]

The Commercial Use of Enzymes

Throughout this project I will be looking at the use of enzymes in industry. I will focus my thoughts onto the medical area and furthermore onto the portable medical devices. This will include looking at biosensors in great detail along with medical test strips.Enzymes are chemical catalysts; this means that they increase the rate of […]

Application of enzymes in industry and medicine

Enzymes have enormous potential in the commercial world. Since they can catalyse specific reactions at relatively low temperatures, they are more versitale and cheaper than inorganic cataylstys. Enzymes can work out a range of Ph levels and normal atmospheric pressure therefore energy saving. Enzymes are biogradable and therefore cause less environmental pollution.Enzymes are formed from […]

What are enzymes

Enzymes are proteins that act as catalysts. They speed up the chemical reactions which occur inside living things. Without them, all reactions would be far too slow, and living organisms would not be able to function. Enzymes are extremely efficient at doing their job. Some of the chemical reactions, which take place in our cells, […]

To examine the effect of temperature on the enzyme catalase

At the most basic level, enzymes are biological catalysts. They are proteins, meaning that they are polymers of amino acids. Their tertiary structure gives them a globular form due to the bonding present in the molecule. Many types of bonds hold the structure together and in the right shape. They strongest of these are the […]

Application of enzymes in Brewing

Enzymes are commonly used in our every day lives and are taken for granted they are used in such things as baking, detergents, food manufacture, fruit juice, oil and fat synthesis, pharmaceuticals, protein production, starch and sugar production, wine making and what I’m looking at, which is brewing. I’m looking at the amount of naturally […]

Have the uses of enzymes in industry and medicine

They have a very high catalytic efficiency and can speed up the chemical reactions by lowering down the activation energy. The enzymes work by a process called the ‘lock and key mechanism’ by fitting in the specific molecules in the active site and then releasing them after the reaction. Enzymes play a very important role […]

The Use of Enzymes in Medicine

Enzymes are biological catalysts, which speed up the rate of a chemical reaction. They speed up the reaction by lowering the activation energy required to begin the reaction. Enzymes work at their optimum rates in specific temperatures and pH ranges. Enzymes are globular proteins with a tertiary structure, which determines the shape of its active […]

The effect of enzyme concentrations on the reaction time

My aim of this investigation is to investigate the effect of enzyme Urease concentrations on reaction time. Urease is the enzyme used to breakdown urea into carbon dioxide and ammonia. I have chosen to carry out this investigation because there are many different areas of biology linked with this investigation that are of interest to […]

Effect of temperature on effectiveness on the Activity Pectinase

I predict the higher the temperature the greater the volume of juice production until a certain temperature where the enzyme denatures. There will also be a temperature where the enzyme works best; this is known as the optimum temperature. This is due to various reasons, ranging from the enzyme’s structure (shape), its properties and its […]

The Uses of enzymes in industry and medicine

Enzymes are Biological catalysts which allow the chemical reactions of metabolism to take place so therefore controlling the speed of the reaction. They are found in all living cells and are divided into two main groups, intracellular and extra cellular. Intracellular are found and work inside the cells, therefore are secreted inside the cell membrane, […]

Salivary Amylase

Salivary amylase, found in humans, is enzyme that catalyzes the hydrolysis of starch into simpler compounds. Its enzymatic activity is affected by several factors, such as temperature and pH. The rates of enzymatic activity of salivary amylase in different temperatures and pH were measured and resulted to be very near 50 C and 7 respectively. […]

The Part Played by Enzymes in the Functioning of Different Cells, Tissues and Organs

Enzymes are protein, they are used to catalyse metabolisms in all organisms. They break down complex molecules and build up complex molecules from simple molecules, these two processes are catabolic reaction and anabolic reaction respectively. Enzymes are needed in these two processes to catalyse releasing and taking up ATP molecules. Different sequence of amino acid […]

Enzyme Lab Report Analysis

The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes, specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However, the activity of an enzyme can […]

Bio Enzyme

Cheese comes in a wide variety of flavors, textures and styles, but the process for making all cheeses remains basically the same. All types of cheeses requires almost the same processes, but there are many different factors that influence how the finished product tastes, textures and smells. The climate of the area where the cheese […]

The Effects of Temperature and Ph on Enzymatic Activity

An enzyme is a molecule that is a biological catalyst for chemical reactions in the body. Most are in the category of proteins, however a few molecules called ribozymes can also catalyze reactions. Enzymes use a specific reactant called substrates to produce products. Without the use of enzymes most of the biological reactions would occur […]

Immobilization of Alpha Amylase

A biocatalyst is termed immobilized, if its mobility has been restricted by chemical means. Immobilization of enzymes refers to techniques which represent variety of advantages over free enzyme catalysis including increased stability of enzyme, easy recovery of enzyme, easy separation of reactant and product, repeated or continuous use of a single batch of enzyme1 (Varavinit […]

Factors that affect Enzyme activity

I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts – catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific […]
