... Biology coursework: enzymes Planning Aim: To see the effects of amylase on starch at different temperatures and to find at what temperature amylase will work best at breaking down starch. I will change the temperature to find this out. Prediction: As the temperature increases, the rate of reaction will increase, because the particles will collide more and speed up the reaction, but if the temperature goes too high then the enzyme will denature. I also predict that the enzymes will not work above 45 °C, they will work best at 37 °C (body temperature). Scientific knowledge: Enzymes are proteins, they break down bigger molecules into smaller ones. They control the chemical reactions that happen in our bodies. They are biological catalysts (A catalyst is a substance which speeds up a reaction without getting used up). There are two types of enzymes, intracellular, which control reactions inside our cells and extra cellular, which
