Unformatted text preview: 1 College of Health & Science School of Biomedical & Health Sciences 300540 Biomolecular Dynamics Assignment 1 Due Date: 1 PM, Tuesday14 th April 2009 in 10.G. 02B. LR08B 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.
