inhibitors, pH and temperature. Calculate rate. NB Whilst covering the theory of all variables which affect reactions, conduct one of the suggested practicals or ISAs as a full investigation in the next section. Calculate rate of reaction from graphs and raw data and explain the advantage of using initial rate. Interpret graphs of enzyme-controlled reactions and apply knowledge to explain them. AT a/AT l – use apparatus, including data loggers, to record measurements eg pH, temperature MS 0.1 – work out and use appropriate for rate MS 0.5 – calculate pH from data about hydrogen ion concentration, using the formula: pH = −log10 [H+] AO2/AO3 and PS1.2 – apply knowledge to practical contexts MS 3.2/3.3 – plot two variables on graphs. Sketch the shape of a graph with a linear relationship using the formula y = mx +c eg the effect of substrate concentration in the presence of excess enzyme 8.4.2.1, 8.4.2.2 and 8.4.2.2.
