An investigation into the effect of temperature on lactase immobilised enzymes in an enzyme controlled reaction Aim: To investigate how a change in temperature will affect the rate at which lactase enzyme will hydrolyse lactose disaccharide sugar into glucose and galactose monosaccharide sugars. Background: Enzymes are biological catalysts which speed up chemical reactions but do not get involved in the chemical reaction, they remain unchanged. Enzymes are large and complex molecules that are synthesised by the cell to perform a specific function. These biological catalysts are very important because they speed up the rate of reaction at which they catalyse, otherwise the chemical reactions that take place in all living organisms would be too slow to support them. Enzymes are specific, they only catalyse one substrate. Enzymes have a three-dimensional shape due to the way the amino acid chain that makes up the chain is folded. This is the tertiary protein structure. Several amino acid...
