…efficiency to catalyze the reaction. We measured the rate of reaction, by using a chromogenic substrate, PNPP, and a spectrometer to determine the amount of product produced in 15 min and also using our normal curve created of known PNP concentrations…

…This experiment will be an investigation into enzyme activity. Wherever enzymes are used one has to bear in mind that there are various factors which affect the enzyme activity. I will be investigating how different concentrations of the enzyme catalase…

…of glucose, the more weight the piece of potato will lose, and when placed in a more dilute glucose solution, the potato will gain weight. This is due to Osmosis, the movement of water molecules from an area of high concetration to an area of low concentration…

…An Investigation into how the Concentration of Substrate will affect the Rate of an Enzyme Controlled Reaction Introduction I am going to investigate how the concentration of hydrogen peroxide affects the rate of reaction between the hydrogen…

…Should we be concerned about the increasing concentration of ownership in the British press? Concentration of ownership is a widely discussed issue in today's society and has been looked and written about by a wide number of people. Colin Seymour-Ure…

…GCSE SCIENCE COURSEWORK (CHEMISTRY) PLANNING: Skill Area P Write down the aim of your Investigation. To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your…

…of reaction. They are:cofb fbr sefbfbw orfb fbk infb fofb fb; · Enzyme concentration: if there are more substrate molecules then there are enzyme molecules, the available number of active sites becomes a limiting factor. The concentration factor reaches its…

…Introduction I am going to investigate how the concentration of hydrogen peroxide affects the rate of reaction between the hydrogen peroxide, and it's enzyme, catalase, which is found in yeast. There are many other factors which will affect the speed…

…Aim: The effect of the salt concentration of water on the productivity of Lupin plants over a fortnight. Hypothesis: Lupin plants that are watered with more salt will be least productive because an increased salt concentration in the water increases…

…Planning In this experiment I am going to find out how concentration of acid affects the rate of reaction with magnesium ribbon. Equation for this reaction: Mg + 2HCl --> MgCl2 + H2 Prediction In this experiment I think the higher…
