    proportional to concentration and the higher the concentration‚ the higher the absorbance. This experiment incorporated Beer’s Law and is focused on determining the stress that various alcohols have on biological membranes. Using five solutions of differing alcohol concentration for each of the three alcohols; methanol‚ ethanol‚ and 1-propanol and a small slice of beet‚ the stirred solution was placed into a plastic cuvette and then into a spectrophotometer and the absorbance of alcohol solutions were

    Investigating the Effect of Concentration on the Rate of Enzyme Catalysed Reaction  To investigate the effect of concentration on the rate of enzyme  catalysed reaction I must know all the factors that affect it in order  to investigate in this.  Here are all the factors:  Temperature- Enzyme like it warm but not too hot. Enzymes are  biological catalysts‚ which speed up chemical reactions. They work  most efficiently at the optimum point (37°C). If they are below 37°C  they will work

    respiration‚ or fermentation. In specific‚ how the type of sugar affects the rate of fermentation. The aim of this experiment was to find which type of sugar was best suited to produce ethanol. In the experiment‚ four different sugars were used‚ they included sucrose‚ glucose‚ lactose and fructose. This research is still relevant today‚ as alcohol is still consumed and is required on a large scale. This makes it crucial to companies to find the best sugar to use in the fermentation process.

    VARYING EFFECTS OF ENZYME CONCENTRATION ON REACTION RATES OF MALATE DEHYDROGENASE CELL BIOLOGY 13 NOVEMBER 2007 Enzymes are biological catalysts. They are proteins that speed up reactions with low concentrations. These enzyme proteins are made up of linkages of amino acids. The links coil‚ and coil again forming a tertiary structure. This structure has a groove in it called an active site. The active site is

    In the yeast discovery lab we had to decided what the outcome would be then perform the experiment. The experiment was done during class time‚ so everyone’s results would be the same. There were four bottles with warm water in them and to those bottles were added yeast. Then to one of each bottle there was added sugar‚ corn syrup‚ corn starch. To the fourth bottle there was only yeast added and used as a control group. Balloons were then stretched onto the top of the bottles to catch any gas the

    Aim: This experiment will aim to show how the amount of substrate affects the rate of the reaction. Hypothesis: In this experiment I think the amount of substrate will simply increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled
