Investigating the factors which affect the rate of enzyme catalysed reactions. Introduction: I aim in this investigation, to explore the factors which affect the rate of enzyme catalysed reactions. I will do this by experimenting with small pieces of potato and how temperature affects the rate of this reaction. I decided to use temperature as my variable because it is easy to regulate but would be difficult to keep constant if I was changing a different factor. Background theory: An enzyme is a biological catalyst, it can alter the rate of reaction without being changed itself. Enzymes are proteins; they have a very precise three-dimensional shape, which forms a specific site on the enzyme. Each enzyme can only convert one kind of substrate molecule in to one kind of product molecule. These are specific. Enzymes are made inside cells but only some exert their action inside the cell. These enzymes are called intracellular enzymes and enzymes which...
