Chemical reaction

Enzymes are proteins that catalyse chemical reactions by the lowering activation energy and speeding up the rate of reaction. The absence of enzymes would result in substantially slower reactions; life would not be sustainable since chemical reactions required for maintaining life would not occur fast enough, (BBC, 2017). Enzymes are not used up in chemical reactions as they are catalysts, not reactants, therefore they can be reused and remain unchanged. Additionally, enzymes are shape specific

walk down the street you are surrounded by chemistry. It is responsible for how many things work for example how your car gets you to school, how soaps clean you, and even how your cell phone charges. But one of the most profound and common chemical reaction that occurs is to formation of rust. Rust is a reddish-brown compound called iron oxide (Fe2O3). This is formed when iron is in contact with oxidant or acids. For iron to rust you must have water and oxygen. As the first drop of water touches

cycle and the process and reactions that take place throughout. Copper is present in several biological systems, having both biological and environmental implication. Sets of experiments will alter copper into nitrate salt, then a hydroxide, followed by an oxide and sulfate, before reaching the state of metallic copper once. These reactions are managed to test the copper in its ionic and the elemental kind, as well as any fluctuation of copper 's reactivity in different chemical environments. Materials

Chemical reactions will take place at the active site. The substance or substances that bind to the active site are called substrates. An enzyme- substrate complex is created after a specific substrate connects with the active site. Covalent bonds in the substrate

enzyme is a biological catalyst that can speed up a chemical reaction by lowering the activation energy. Typically the lower the activation energy the faster the reaction will be. It's made up of a plethora of different types of proteins that forms into a 3D like shape. Enzymes are very important to the human body, because it keeps the chemical activity that undergoes in our body at a low temperature. Enzymes need substates in order to have a reaction and be able to form a enzyme-substrate complex. To

In this lab experiment, an unknown metal carbonate went through a chemical reaction with 1.0 M barium chloride, forming products of barium carbonate and an alkali metal chloride. The unknown alkali metal carbonate also went through a chemical reaction with 1 M hydrochloric acid, forming an alkali metal chloride, with liquid water, and carbon dioxide gas as products. A final flame test was done to reveal what the unknown alkali metal was. Once all molar masses were calculated, the masses were extremely

Even through filtration shows its effectiveness, biological and chemical treatments still a significant process as greywater is required further treatment to remove organics, nutrients and surfactants in greywater (Li et al., 2009). In terms of chemical treatments for greywater, there is limited studies have been done so far, only a few technologies such as electrocoagulation (Li et al., 2009). According to Vakil et al. (2014), Electrocoagulation (EC) known as an electrochemical technique, when water

Enzyme is proteins that speed up and regulate the process of chemical reactions within living organisms. Enzyme helps to reduce reaction rates by breaking bonds between atoms (). Biochemical reactions require energy. The minimum amount of energy is necessary to set atoms be able to undergo chemical reactions is called activation energy (Activation energy, 2015). When reactants absorb energy and reach to the activation energy, reactants combine and produce products. According to Campbell et al. (2009)

in the presence of a catalyst, which would speed up the rate of reaction. In this reaction Glucose would react with water to produce Carbon Dioxide (CO2) and Water (H2O). Methylene blue was an indicator that turned blue as it reacted with the Oxygen in the water. In a perfect case scenario, the dissolved oxygen in the water would cause the Methylene blue to turn blue. As the reaction takes place, the oxygen is consumed in the reaction as glucose is oxidized to form carbon dioxide and water thus, turning

Turnips and horse radish roots are rich source of this enzyme. In this experiment, we would carry out a reaction between hydrogen peroxide and guaiacol which is colorless dye, using peroxidase as a catalyst, to produce water and an oxidized form of guaiacol which is brown. The formation of brown color would serve as an indicator that the breakdown of Hydrogen
