Biology Enzymes Coursework Essay - 569 Words

Biology Enzymes Coursework Prediction: I think that the enzyme will work best at 45.c to 50.c I think this because that optimum temperature for most natural enzymes is 40.c but his is a chemical enzyme so it will work best a little higher. If this temp is exceeded then I think that it will take longer to work because it will not be at the optimum temp, or it will not work at all because it has become denatured. An enzyme cannot recover from this state. Below this temperature I think it will be slowed down but will not denature because it cant at low temperatures only at high ones. These will not be to reliable so I may have to use a different set of measurements when I do†¦show more content†¦(Better explained in my picture) Key when joined the reaction starts, Active site (lock) This reaction will not work because the Key lock doesnt fit the key. This will never work again. Active site (lock denatured) As you can see as soon as the lock gets denatured it wll no longer work. Preliminary work: I watched someone else do this experiment and saw how it was to be done. This helped me see how the experiment worked and how to do things correctly. I also have done a lot of work on enzymes in lessons and know how they work which has helped me understand this process. Results: Temperature in .c 1st time in minutes 2nd time in minutes 3rd time in minutes Average time 20 30 40 50 10+ 60 10+ 10+ 10+ 70 10+ 10+ 10+ There are too many negative results because the enzyme is denaturing too quickly, so as I thought I would have to narrow my temperatures to, 20.c, 30.c, 40.c, 45.c, 50.c and 60.c. This is my new results table.

Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. Each enzyme just performs one particular reaction so they are all very specific. Catalase enzymes found in living cells e.g. in yeast, potato or liver, speed up (in our case) the breaking down of hydrogen peroxide.

Inhibitors are chemicals, which inhibit the action of an enzyme. There are two main types of inhibitors: reversible and non-reversible. Non-reversible inhibitors permanently damage enzymes.
