Integrating the flux–flux autocorrelation function yields this quantity, which is estimated by the quadratic Morrison equation when the free ligand assumption fails to hold. Manfred Eigen pioneered a class of techniques for use when this quantity is very high, which are named for the “jump” of various parameters. The reciprocal of one form of this quantity is plotted on the y-axis of a Lineweaver–Burk plot. (10[3])One specific form of this quantity denoted V-max (10[1])is found (10[1])in the numerator of (10[1])the Michaelis–Menten equation, which is used to calculate a form of this quantity. “Integrated” forms of statements about this quantity plot various functions of concentration against time. For 10 points, name this quantity governed by a namesake constant k, (10[1])which measures how fast a reaction proceeds. ■END■
