Non-relativistic Energy Spectrum of the Deng-Fan Oscillator via the WKB Approximation Method

Ekwevugbe Omugbe · Asian Journal of Physical and Chemical Sciences · 2020

The energy spectrum of the radial Schrodinger equation with the molecular Deng Fan potential has been obtained through the WKB approximation scheme. The radial WKB solution yields a transcendental or an implicit equation. The energy eigenvalues for non-physical and real molecular...

Enzymatic Kinetic Issues and Controversies Surrounding Gibbs Free Energy of Activation and Arrhenius Activation Energy

Ikechukwu I. Udema & Abraham Olalere Onigbinde · Asian Journal of Physical and Chemical Sciences · 2020

Background: The equation of the difference between reverse and forward Gibbs free energy of activation (ΔΔGES#) reflects Michaelis-Menten constant (KM) in both directions; this may not be applicable to all enzymes even if the reverse reaction is speculatively Michaelian. Arrheniu...

Derivable Equations and Issues Often Ignored in the Original Michaelis-Menten Mathematical Formalism

Ikechukwu I. Udema · Asian Journal of Physical and Chemical Sciences · 2019

Background: There has been recent shift from the core issue of Michaelian kinetics to issues regarding various kinds of quasi-steady-state assumptions. Derivable equations with which to determine reverse rate constant for the dissociation of enzyme-substrate complex (ES) is given...
