Plan The effect of temperature on enzymes Research Enzymes are proteins that control important biological processes. In the human body, enzymes are used to control the break down of food and control reactions which make products like fats, carbohydrates, proteins and DNA. Enzymes can also control the rate of which chemical substances are built up. Chemical compounds are made up of smaller units called molecules. Each enzyme has its own complicated shape; it can only react with one type of molecule called its substrate. The enzyme's shape must fit into this substrate's shape exactly (a bit like a key). If anything changes this fit, it will alter how well the enzyme works. When enzyme and substrate molecules meet, they can react. In solution, molecules move around freely. If the substrate is the correct shape for the enzyme, they will meet, if it's the wrong shape then they collide. If the temperature is...
