Free biology coursework papers, essays, and research papers biology enzymes coursework - biology enzymes coursework prediction: i think that the enzyme will work best at 45c to 50c i think this because that optimum temperature for most natural enzymes [tags: gcse biology a2 a-level coursework], 591 words. Graphs like the one shown below (graphing reaction rate as a function of substrate concentration) are often used to display information about enzyme kinetics they provide a lot of useful information image modified from enzymes: figure 3, by openstax college, biology (cc by 30) imagine that you have your favorite.
The amount of energy necessary to start a biochemical reaction is called activation energy special proteins called enzymes lower activation energy, allowing life to exist in this lesson, explore how enzymes work and see what conditions affect them. An enzyme inhibitor is a substance that slow down the rate at which an enzyme- catalyzed reaction take place competitive inhibitors (aka active site-directed inhibitors) have a shape similar to the enzyme's normal substrate they bind suitable for: edexcel biology a level modules 5 or 6, but also other exam boards. Data task coursework- enzyme and temperature as a class we collected the optimum temperature is the temperature at which an enzyme produces the highest reaction rate after the optimum should be plotted on a graph, with an x-axis marked as ph levels and the y-axis marked as enzyme activity.

Here is an example of a-level biology coursework on the effect of substrate concentration (hydrogen peroxide) on the rate of activity of the enzyme catalase. Enzyme active site and substrate specificity enzymes catalyze chemical reactions by lowering activation energy barriers and converting substrate molecules to products.
