one product causing an anabolic reaction. There are five factors that effect enzyme activity. They are: ·Temperature ·pH ·Inhibitors ·Substrate Concentration ·Enzyme Concentration The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato‚ you make more Catalase molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between the enzyme

The origin of high hydraulic resistance for filter cakes of deformable particles: cell-bed deformation or surface-layer effect? M. Meireles‚ C. Molle‚ M.J. Clifton‚ P. Aimar Laboratoire de Génie Chimique (CNRS UMR 5503)‚ Université Paul Sabatier‚ 118 Route de Narbonne‚ 31062 Toulouse cedex‚ France Abstract This study reports a numerical approach for modeling the hydraulic resistance of a filter cake of deformable cells. First‚ a mechanical and osmotic model that describes the

The content will be based on 3 key discussion points supported with references – why understanding surface and deep level diversity is a good practice for manager‚ why is it important to manage for diversity in Singapore‚ and lastly the distinct characteristics of Singaporean employees that need to factor‚ compared to other expatriates.

What is the Marine Ecosystem? Marine ecosystems are among the largest of Earth’s aquatic ecosystems. It covers almost 70% of the earth’s surface. They include oceans‚ salt marsh and intertidal ecology‚ estuaries and lagoons‚ mangroves and coral reefs‚ the deep sea and the sea floor. They can be contrasted with freshwater ecosystems‚ which have a lower salt content. Why is the Marine Ecosystem important? Marine ecosystems are very important in to the overall health of both marine and terrestrial

electrostatic equilibrium is that the electric field anywhere beneath the surface of a charged conductor is zero. If an electric field did exist beneath the surface of a conductor (and inside of it)‚ then the electric field would exert a force on all electrons that were present there. This net force would begin to accelerate and move these electrons. But objects at electrostatic equilibrium have no further motion of charge about the surface. So if this were to occur‚ then the original claim that the object

illustration of the principle of Biacore SPR to measure the interaction between analyte molecules in the flow with immobilized receptor binding sites on the surface. A) SPR uses an optical method to measure changes in the refractive index near the surface of a thin gold film on a glass slide. At a critical angle of incident light on the surface-solution interface an electromagnetic field or evanescent wave is generated. This is detected as absorption of light and a decrease in the intensity of the

Discussion: In this experiment‚ the factor that is evaluated is the Ra value‚ which is the mean deviation of the peaks from the centre line of the trace. In the case surface is considered smooth if the Ra value is equal or less than 0.1m. From the result of these experiment‚ we can say that different of the theoretical data and experimental value is very large. This is happen because value of n is not big enough to get accurate result. In this experiment we only that n=5 that’s make the huge different
