A plot of some linear relationship between reaction rate (v) and substrate concentration (S) is commonly used to estimate the constant,s of an enzyme system that follows the Michaelis-Menten theory of enzyme action. In cases in which there is certainty that only one enzyme is involved, it suffices to apply such a plot over a relatively short range of substrate concentrations. This certainty doe...

Using an electronic spectrum of I2, Deslanders table and Birge-Sponer plots, vibrational and electronic parameters were calculated. The vibrational frequency, anharmonicity constant, dissociation energy and the equilibrium dissociation energy for the ground state were found to be 221.103 cm, 0.0119 cm, 12189 cm and 12300.2 cm, respectively. The vibrational frequency, anharmonicity constant, dis...

The statistical implications of the direct linear plot for enzyme kinetic data, described in the preceding paper (Eisenthal & Cornish-Bowden, 1974), are discussed for the case of the Michaelis-Menten equation. The plot is shown to lead directly to non-parametric confidence limits for the kinetic parameters, V and K(m), which depend on far less sweeping assumptions about the nature of experiment...

Charge movement was measured in frog cut twitch fibers with the double Vaseline-gap technique. 25 microM tetracaine had very little effect on the maximum amounts of Q beta and Q gamma but slowed the kinetics of the I gamma humps in the ON segments of TEST-minus-CONTROL current traces, giving rise to biphasic transients in the difference traces. This concentration of tetracaine also shifted V ga...

The main goal of this research work was to detect the different Cu mineralized zones in the Sungun porphyry deposit in NW Iran using the Spectrum-Volume (S-V) fractal modeling based on the sub-surface data for this deposit. This operation was carried out on an estimated Cu block model based on a Fast Fourier Transformation (FFT) using the C++ and MATLAB programing. The S-V log-log plot was gene...

1. A theoretical appraisal of the alternative pathway mechanism for a two-substrate enzyme shows that this mechanism is capable of giving rise to apparent substrate inhibition or substrate activation (Dalziel, 1958). It has now been shown that these phenomena may occur simultaneously in the following ways. With certain relationships between the kinetic parameters and the constant concentration ...

A "V"-shaped Hammett plot shows that resonance-assisted hydrogen bonding does not dictate the strength of the intramolecular hydrogen bond in the E isomers of hydrazone-based switches because it involves an aromatic pyridyl ring.
