Investigate the effect of enzyme concentration on the rate of reaction

- To investigate the effect of enzyme concentration on the rate of reaction PREDICTION: An enzyme is a biological catalyst. They speed up the rate of a reaction however they do not affected themselves whilst doing this, which is why they are catalysts. Enzymes are made to be specific, this means that they can have only one substrate that they will work on. Each enzyme has an active site that is where their own specific substrate’s molecule will fit into. The enzymes catalyze chemical reactions beginning with the binding of the substrate to the active site on the enzyme....   [tags: GCSE Chemistry Coursework Investigation]

Archimedes Principle: Any object wholly or partly immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. Density is mass of a unit volume of a material substance, expressed as kilograms per cubic meter in MKS or SI units.

Gas Chromatography

- Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to be a substance that is either in a liquid or a gas state....   [tags: essays research papers]

injection molding

- Wilbert Plastic Services In the early days manufacturers came to us for a specific thermoformed or injection molded part or parts for a product they were making. Over the years we noticed that, more and more, they were coming to us for entire subassemblies and more complex parts that might incorporate both thermoformed and injection molded parts. Based on that experience, and our knowledge of the pressures that manufacturers are under to increase efficiency and reduce cost, it became obvious to us that we needed to provide a wider array of services to help our customers increase their efficiencies, reduce their overall costs and maximize their ROI on each project, part or component....   [tags: essays research papers]

Lava Flows

- Lava Flows There are two types of lava flows, free flowing mobile lava and slow moving viscous lava. Free flowing mobile (basaltic) lava creates a vent and spreads to produce large broad cones called shield volcanoes. The slow moving viscous (rhyolite) lava creates a narrow steep-sided cone due to a different chemical composition to basalt and this makes the lava flows more slowly down the cone side. My Aims My aims are to investigate the factors affecting Lava Flows. There are lots of factors affecting a lava flow, they are: 1....   [tags: Papers]

Superchargers

- Superchargers A supercharger, often referred to as a “blower”, is a mechanism for forcing or “blowing” air into an internal-combustion engine in order to increase engine power. The power of an engine is directly related to the amount of air it can consume, mix with fuel, and burn in its cylinders, and therefore the more air that can be forced into the engine, the more power the engine can produce. However, in a non-“blown” engine, only a certain amount can be forced in. In order to understand the workings and importance of a supercharger, we must first be familiar with how a normal or stock engine’s intake works....   [tags: Mechanics Engines Automobiles Essays]
