Biology Coursework Investigating Catalyse Activity Chris Weeks 10Y3 Aim To investigate and understand the rates of enzyme activity using five different concentrations of catalyse on a potato as an example. Research In order to understand and carry out the investigation correctly, I have researched material appropriate to it. * Starch, proteins and fats are large, insoluble food molecules. * Even after the teeth have torn them, and the stomach has churned them, they are still too big and insoluble to pass through the blood stream. * They are broken down using enzymes. * Enzymes are specific, meaning they fit the substrate. * They are also catalysts and speed up the rate of reaction. * In digestion there are three important enzymes. Food Group Enzyme Building Blocks Proteins Protease Amino acids Carbohydrates Carbohydrase Sugars Fats (Lipids) Lipase Fatty acids and Glycerol * The building blocks are what the Food group are made up of. * Starch is broken down into glucose in the mouth and small intestine. * Proteins are broken down into amino acids in the stomach...
