Investigating the Effect of Lipase Concentration on the Breakdown of Fat in Milk INTRODUCTION: Enzymes are proteins which can catalyse chemical reactions without changing themselves. The enzyme lipase breaks down the fat in dairy products such as full-cream milk for people who are lactose intolerant. Lipase acts on its specific substrate‚ lipids produces fatty acids. If enzyme concentration increases‚ random collisions between the substrates and active sites of enzyme increase due to the increasing

Case study A blue paint layer sample was collected from the wall decorations of the mortuary temple of Ramesses III (Medinet Habu. This temple is one of the largest memorial temples in Egypt. It measures 320 m in length (east to west) and about 200 m in width (north to south)‚ built with order of the Pharaoh Ramesses III (c.1184–1151 BC the 20th Dynasty). The micro-XRF spectrometer (SPECTRO‚ COPRA model) used to analyze the sample includes a side-window X-ray tube with Mo anode (Oxford Instruments

Background Research Yeast are eukaryotic microorganisms just like other organisms‚ they must respire in order to survive. Respiration can be defined as the controlled release of energy from organic compounds to form adenosine triphosphate (ATP). The type of respiration that occurs is called aerobic respiration. It occurs when glucose and oxygen are present. It can be summarized by the equation: . Enzymes play a very significant part in respiration. During the different stages of respiration‚ enzymes

The first is the quality of the calorimeter. With a simple plastic lid‚ our cheap colorimeter is relatively effective for a low cost but without a proper seal and adequate insulation some of the heat from the reaction was transferred to the surrounding environment instead of the liquid in the cups. This would cause our experimentally collected

Task 3 – D Why is it important for all laboratory procedures and practices to be followed and communicated through the team? Chemical Store management – it is vital for chemical storage procedures to be followed as the potential risks that can result from using and handling chemicals can be very high. For example; mishandling of citric acid (even though it is a low risk chemical) could result in contact with the skin and/or eyes which may cause irritation‚ miscommunication between the staff could
