cell membrane. The cell Membrane is a thin protective coating around a cell that regulates what goes in and out of the cell. An important part of regulating this is passive transport. Passive transport is the movement of materials through membranes without any input of energy. One type of passive transport is diffusion. Passive transport is the diffusion of substances across a membrane. In diffusion‚ molecules will usually move from where the substance is more concentrated to where it is less

Biology Coursework: Preliminary Work 8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules
