Each enzyme lowers the activation energy of the reaction it catalyses. The induced-fit model of enzyme action. The properties of an enzyme relate to the tertiary structure of its active site and its ability to combine with complementary substrate(s) to form an enzyme-substrate complex.
Students should be able to:
| MS 0.5 Students could be given the hydrogen ion concentration of a solution in order to calculate its pH, using the formula: |

Required practical 1: Investigation into the effect of a named variable on the rate of an enzyme-controlled reaction. | PS 2.4 Students could identify the variables that must be controlled in their investigation into rate of reaction. PS 3.3 Students could calculate the uncertainty of their measurements of the rate of reaction. MS 3.2 Students could select an appropriate format for the graphical presentation of the results of their investigation into the rate of enzyme-controlled reactions. MS 3.6 Students could use a tangent to find the initial rate of an enzyme-controlled reaction. |
