acts on a molecule called substrate and it also significantly speed up a chemical reaction by lowering the activation energy. In order to learn about the enzyme and its behaviour‚ this lab practical is conducted to examine the kinetic of the enzyme alkaline phosphatase. As illustration‚ when alkaline phosphatase is added to a substrate called p-Nitrophenyl phosphate (colourless in alkaline solution)‚ a series of reaction takes place and eventually releases a product called p-nitrophenol (yellow in alkaline

knee implant. Each has its own benefits and disadvantages‚ because of this each material is utilized for a different part of the knee replacement. The three parts of the knee replacement are depicted in Figure 1 and are the femoral component‚ the plastic surface‚ and the tibial plate. The material that is the best fit to use for a biodegradable friendly knee replacement wouldn’t be a metal‚ though currently most common used‚ because when metals degrade the particles are smaller in size and greater in

Abstract The photocatalytic degradation of phenol has been tested primarily with titanium dioxide (TiO2) either alone or in combination with other materials. In this work‚ Mg/Al hydrotalcites prepared by two methods using inorganic (HC) or organic (HS) chemical reagents‚ along with mixed oxides produced by calcination of these products (HCC and HSC) were mixed with titanium isopropoxide to obtain hydroxide-TiO2 compounds (HCC-TiO2 and HSC-TiO2) to test their photocatalytic activity compared with

Total Hip Replacement As similar to every other surgery‚ the hip replacement surgery also demand a careful examination and procedure. The Minimally Invasive Computer Navigated Hip Replacement Surgery is the modern version for the traditional total hip replacement. During the surgery‚ cut is prepared through the hip covering hip. After this initial step‚ simulated implants are implanted. The incision made is often small ranging from 3 to 6 inches. This size is completely subjective on patient’s structure

Purpose The purpose of this experiment is to determine the rate constants‚ k1‚ for the methyl acetate hydrolysis reaction at 25 °C and 35 °C‚ as well as the overall activation energy of the reaction. Methods Methyl acetate was placed in an HCl solution‚ in which it reacts with water to form acetic acid over time. At each time interval‚ an aliquot of the mixture was removed for titration against NaOH to determine the concentration of the acetic acid produced. From the amount of acetic acid produced

Single Mothers: The Single Handed Struggle When thinking of the perfect family‚ most people think of either a family close to them or what seems to be the generic traditional view of the perfect family; two parents‚ two or three well-mannered and behaved kids and a dog running through a green backyard behind a house with a white picket fence. For some people this lifestyle is all they have known and grown up with. For the majority of the rest of the country‚ this picturesque idea is seen through

Fossil fuels have been the main component used to get the source of energy for decades around the world where relying on the use of it has became a way of life. Kristinstand in Sweden‚ Europe‚ has substituted fossil fuels over a decade ago with biogas‚ which greatly decrease harmful carbon dioxide emissions‚ meaning it would not contribute to global warming. Harnessing renewable energy effectively can be done if the resources are present and there is support from the government. this essay will consist
