Factors affecting Enzymes 0.0 / 5 ? BiologyEnzymes and digestionGCSEAQA Created by: asho glenoCreated on: 13-04-15 16:54 1. Temperature - The optimum temperature for enzymes in the body is... 37 oc 1 of 10 Below this temp, the rate of reaction drops as... the molecules have less kinetic energy 2 of 10 Above 40 oc, the enzzymes begin to denature and this... changes the active site so that it is no longer coplimentary to id's substrate 3 of 10 This change is then... permanent 4 of 10 In normal conditions, the enzyme and substrate parrticles move faster... as the teemperature increases, making them more likely to collide with enough energy to react 5 of 10 2. pH - Enzymes are affected within a very small... range of pH, usually denaturing with 3-4 6 of 10 Once denatured, the change... is permanent 7 of 10 The shape of enzymes is due to the forces between the different parts of... the protein molecule which hold the folded chains in place 8 of 10 A change in pH affects these forces and changes... the shape of the molecule, making the active sight lost 9 of 10 Proteins can be used for buiding/strcutural material,hormones... antibodies and catalysts 10 of 10
