What are enzymes? Enzymes are generated by a living organism that behaves as a catalyst to carry out a clear biochemical reaction. Enzymes increases the rate of chemical reactions by lowering the free energy barrier that separates the reactants and products.Enzymes are the tools of nature and they help in breaking down our food. They speed up all necessary biological activities. The enzymes in the stomach, as an example make certain that food is break down into smaller fleck that can be transformed into energy in the body. Wherever a substance needs to be converted into any other substance, nature put to use the enzymes to increase the speed of the process. Enzymes are the workhorses of the body. When we eat, enzymes break down the food into smaller particles which can be changed into energy in the body. The activity starts in the mouth, where an enzyme called amylase strike all incoming food flecks. The collapse of food is a vital part of the transformation of food into energy. Undigested food is unfit to pass on the energy deposit within it. The enzymes involved in the digestion process carry out the final cutting of the food particles so that they can be easily converted into the essential energy needed by all parts of our body. 1. Mechanism of enzyme action: Enzymes are catalysts. So they help making a biochemical reactions work faster than they would otherwise. Sometimes the required reactions would not occur at all without the support of enzymes. Being catalysts also means that enzymes are not part of the actual product. They make things happen. When the job is done, enzymes are ready to catalyze a new biochemical reaction. Every enzyme has a particular function. One of the unique ... ... middle of paper ... ...n, known as theInitial Reaction Rate is the maximum reaction rate for an enzyme in anexperimental situation. Substrate Concentration • Increasing Substrate Concentration increases the rate of reaction. This is because more substrate molecules will be colliding with enzyme molecules, so more product will be formed. • However, after a certain concentration, any increase will have no effecton the rate of reaction, since Substrate Concentration will no longer be the limiting factor. The enzymes will effectively become saturated, and will be working at their maximum possible rate. Enzyme Concentration • Increasing Enzyme Concentration will increase the rate of reaction, asmore enzymes will be colliding with substrate molecules. • However, this too will only have an effect up to a certain concentration, where the Enzyme Concentration is no longer the limiting factor.

    For example, substrate concentration, enzyme concentration, and temperature could all be factors that affected the chemical reactions in our experiment. The concentration of substrate, in this case, would not have an affect on how the bovine liver catalase and the yeast would react. The reason why is because in both instances, the substrate (hydrogen peroxide) concentration was 1.5%. Therefore, the hydrogen peroxide would saturate the enzyme and produce the maximum rate of the chemical reaction. The other factor that could affect the rate of reaction is enzyme concentration. Evidently, higher concentrations of catalase in the bovine liver produced faster reactions, and the opposite occurs for lower concentrations of catalase. More enzymes in the catalase solution would collide with the hydrogen peroxide substrate. However, the yeast would react slower than the 400 U/mL solution, but faster than the 40 U/mL. Based on this evidence, I would conclude that the yeast has a higher enzyme concentration than 40 U/mL, but lower than 400

    The shape of the molecules is changing and so the enzyme molecules can no longer fit into the gaps in the substrate that they need to and therefore the enzymes have de – natured and can no longer function as they are supposed to and cannot do their job correctly. Changing the temperature: Five different temperatures could be investigated. Water baths were used to maintain a constant temperature. Water baths were set up at 40 degrees, 60 degrees and 80 degrees (Celsius). Room temperature investigations were also carried out (20 degrees).

    Enzymes are biological catalysts, which are proteins that help speed up chemical reactions. Enzymes use reactants, known as the substrates, and are converted into products. Through this chemical reaction, the enzyme itself is not consumed and can be used over and over again for future chemical reactions, but with the same substrate and product formed. Enzymes usually only convert specific substrates into products. Substrates bind to the region of an enzyme called the active site to form the enzyme/substrate complex. Then this becomes the enzyme/products complex, and then the products leave the enzyme. The activity of enzymes can be altered based on a couple of factors. Factors include pH, temperature and others. These factors, if they become

    Changing the concentration of enzymes has a direct impact on the enzyme activity. When enzyme concentration increases so does enzyme activity, and when enzyme concentration decreases so does enzyme activity. Enzyme activity and enzyme concentration are directly proportional up until a certain point where increased concentration will have no effect on enzyme

    Background information:. Enzyme Enzymes are protein molecules that act as the biological catalysts. A Catalyst is a molecule which can speed up chemical reactions but remains unchanged at the end of the reaction. Enzymes catalyze most of the metabolic reactions that take place within a living organism. They speed up the metabolic reactions by lowering the amount of energy.

    The [ES] complex can then undergo two different pathways; the complex can dissociate to [E] and [S], at a rate of k or it can shift equilibrium to the left with a rate constant of k2 to form [E] and product [P]1. In this model, the breakdown of the ES complex to yield P is the overall rate-limiting step. Three assumptions of a Michaelis-Menton plot are that a specific [ES] complex in rapid equilibrium between [E] and [S] is a necessary intermediate, the amount of substrate is more than the amount of enzyme so the [S] remains constant, and that this plot follows steady state assumptions. Steady state assumptions states that the intermediate stays the same concentration even if the starting materials and products are constantly changing.2 The rapid equilibrium between enzyme and substrate, and the enzyme-substrate complex yields a mathematical description regarded as the Michaelis-Menton

    Enzymes are biology catalysts which speed up the rate of a reaction (BBC News). Catalase is an enzyme which is found in one’s body and can destroy any harmful substances. Without catalase, many toxic materials could attack and mutate DNA. Catalase is located in the hepatic and when mixed with hydrogen peroxide, it breaks it down into oxygen and water. When the reaction happens it follows this equation: 2H2O2 → 2H2O + O2 ("Catalase.").

    In this lab, it was determined how the rate of an enzyme-catalyzed reaction is affected by physical factors such as enzyme concentration, temperature, and substrate concentration affect. The question of what factors influence enzyme activity can be answered by the results of peroxidase activity and its relation to temperature and whether or not hydroxylamine causes a reaction change with enzyme activity. An enzyme is a protein produced by a living organism that serves as a biological catalyst. A catalyst is a substance that speeds up the rate of a chemical reaction and does so by lowering the activation energy of a reaction. With that energy reactants are brought together so that products can be formed.

    According to the graph on amylase activity at various enzyme concentration (graph 1), the increase of enzyme dilution results in a slower decrease of amylose percentage. Looking at the graph, the amylose percentage decreases at a fast rate with the undiluted enzyme. However, the enzyme dilution with a concentration of 1:3 decreased at a slow rate over time. Additionally, the higher the enzyme dilution, the higher the amylose percentage. For example, in the graph it can be seen that the enzyme dilution with a 1:9 concentration increased over time. However, there is a drastic increase after four minutes, but this is most likely a result of the error that was encountered during the experiment. The undiluted enzyme and the enzyme dilution had a low amylose percentage because there was high enzyme activity. Also, there was an increase in amylose percentage with the enzyme dilution with a 1: 9 concentrations because there was low enzyme activity.

    Enzymes are types of proteins that work as a substance to help speed up a chemical reaction (Madar & Windelspecht, 104). There are three factors that help enzyme activity increase in speed. The three factors that speed up the activity of enzymes are concentration, an increase in temperature, and a preferred pH environment. Whether or not the reaction continues to move forward is not up to the enzyme, instead the reaction is dependent on a reaction’s free energy. These enzymatic reactions have reactants referred to as substrates. Enzymes do much more than create substrates; enzymes actually work with the substrate in a reaction (Madar &Windelspecht, 106). For reactions in a cell it is important that a specific enzyme is present during the process. For example, lactase must be able to collaborate with lactose in order to break it down (Madar & Windelspecht, 105).
