Measuring Enzyme activity and microscope work. If my replicates had not been so close I would have had to Alevel biology coursework the tube. Consistent Temperature Temperature is a major factor which affects the rate of reaction. This is shown when oxygen stops being produced and the same results are recorded five times.
For this Reason I prefer chemistry since you cant rely on memorizing mark schemes in the exam. Now that I have carried out the repeats and plotted the points on the rate of reaction graph, I can see that the graph is in fact clearly linear. Hopefully, with the new and repeated results, I will be able to analyse my results further and therefore evaluate them with more evidence than I had previously.
Where can I go with a Biology A-Level Students who take A Level Biology can go on to study veterinary science, medicine, optometry psychology, nursing, dentistry, pharmacy, physiotherapy, sports science, microbiology, forensic science, biophysics, genetics, neuroscience, botany, zoology, ecology and environmental science and of course, biology.
If you do not graduate this could cause big problems for your career and most likely mean that you are not able to go into the career that you desire to go into. In addition to this, you should also be familiar with the following: For example, the final average volumes of gas were as follows: Evaluation Overall, I believe my experiment went well and that I gained sufficient results because I repeated each concentration three times and investigated eight concentrations in total.
Rest reassured practicals are not part of an assessment in Edexcel biology. What skills are needed to enrol onto this course?
Surface Area of Yeast Molecules I ground up the yeast to try to make the surface area as similar as possible because surface area is a major factor in my experiment. I believe that the data also shows strong positive correlation, and there are few outliers, which shows that my results are accurate.
This is because the molecules of both substrate and enzyme have more energy, therefore they collide more often and produce more heat energy. I will work out the gradient of these new results and plot them on a new rate of reaction graph. Clean and Dry Equipment I also had to make sure I washed out the conical flask and beaker thoroughly with distilled water and dried them sufficiently.
However, I do not believe the substrate concentrations were significantly different because my repeats were mostly concordant, so a similar amount of oxygen was produced which must mean that there was a similar number of substrate molecules in each concentration. I tried to make this as accurate as possible by keeping my eyes level with the gas syringe.
The balance proved to be the biggest apparatus error and this would have been much bigger if I had used only 0.A handy collection notes to help you study your A Levels.
