College of Health & Science School of Biomedical & Health Sciences 300540 Biomolecular Dynamics Assignment 1 Due Date: 12 PM, Thursday 17 th April 2008 in 10.18 LR23 Hand-drawn graphs are not allowed. Use Excel and give full working and units for all your working steps. Question 1 (This question covers the lectures done in biomolecular kinetics only). 5 Marks a) Distinguish between zeroth-order, first-order, second-order, and pseudo-first-order reactions. 5 Marks b) Explain clearly in chemical terms what you understand by the Michaelis-Menten mechanism. 5 Marks c) The rate v of an enzyme-catalysed reaction was measured when various amounts of substrate were present and the concentration of enzymes was 12.5 x 10 -6 mol L -1 . The following results were obtained (Table 1): Table 1: Data collected for an enzyme-catalysed reaction.
