Ruminally undegraded protein (RUP) values of blood meal (n = 2), hydrolyzed feather meal (n = 2), fish meal (n = 2), meat and bone meal, and soybean meal were estimated using an in situ method, an inhibitor in vitro method, and an inhibitor in vitro technique applying Michaelis-Menten saturation kinetics. Degradation rates for in situ and inhibitor in vitro methods were calculated by regression...

<abstract><p>In this paper, we use a semi-discretization method to explore predator-prey model with Michaelis-Menten functional response. Firstly, investigate the local stability of fixed points. Then, by using center manifold theorem and bifurcation theory, demonstrate that system experiences flip Neimark-Sacker at point when one parameters goes through its critical value. To illus...

We present a model of an ATP-fueled molecular machine which push a polymer through a pore channel. The machine acts between two levels (workingwaiting), and the working one remains active for a fixed time giving a constant force. The machine activation rate can be put in relationship with the available ATP concentration in the solution, which gives the necessary energy supply. The translocation...

In this paper we study a food chain model with three trophic levels and Michaelis-Menten type ratio-dependent functional response. Distinctive feature of this model is the sensitive dependence of the dynamical behavior on the initial populations and parameters of the real world. The stability of the equilibrium points are also investigated. Keywords—Food chain, Ratio dependent models, Three lev...

Here we develop the use of artificial neural networks for solving the inverse metabolic problem, in other words, given a set of steady-state metabolite levels and fluxes in a pathway of known structure to obtain the parameters of the system, in this case the enzymatic limiting rate and Michaelis constants. This requires two main procedures: first the development of a computer program with which...

Abstract. Ectoenzymatic activity, prokaryotic heterotrophic abundances and production were determined in the Mediterranean Sea. Sampling was carried out sub-surface, deep chlorophyll maximum layer (DCM), core of Levantine intermediate waters deeper part mesopelagic layers. Michaelis–Menten kinetics assessed using a large range concentrations fluorogenic substrates (0.025 to 50 µM). As consequen...

Bassingthwaighte JB, Chinn TM. Reexamining Michaelis-Menten enzyme kinetics for xanthine oxidase. Adv Physiol Educ 37: 37–48, 2013; doi:10.1152/advan.00107.2012.—Abbreviated expressions for enzyme kinetic expressions, such as the Michaelis-Menten (M-M) equations, are based on the premise that enzyme concentrations are low compared with those of the substrate and product. When one does progress ...
