Coursework: Aim: To investigate the effect of temperature on an enzyme's (lipase) ability to break down fat. Hypothesis: The graph below shows the rate increasing as the enzymes get closer to their optimum temperature (around 35 degrees Celsius) from room temperature. The enzyme particles are moving quicker because the temperature increases so more collisions and reactions occur between the enzymes and the substrate molecules. After this the graph shows the rate decreasing as the enzymes are past their optimum temperature (higher than). They are getting exposed to temperatures that are too hot and so the proteins are being destroyed. The shape of the molecules is changing and so the enzyme molecules can no longer fit into the gaps in the substrate that they need to and therefore the enzymes have de - natured and can no longer function as they are supposed to and cannot do their job correctly. Changing the temperature: Five different temperatures could...
