Andrew Mackay 12 E As Biology Coursework 2002 Investigate the effect of sucrase concentration on the rate of hydrolysis of sucrose. Skill P - Planning Hypothesis - The digestion of sucrose into glucose and fructose is carried out by the presence of the enzyme Sucrase. The activity of the enzyme will be greatest at its optimum temperature since at this temperature the enzyme's tertiary structure will be correct to allow the formation of the substrate-enzyme complex quickly and efficiently. This should be at 37°C (body temperature), which is the temperature of the ileum where Sucrase is secreted and naturally functions. The first thing to say about enzymes is that they are proteins and they are found in all types of organisms from humans to viruses. They function in the body as catalysts. In other words they speed up the rate of chemical reactions in the body. Enzymes actually accelerate chemical reactions by a factor...
