Get Price2011-6-29 · The basic model of coupling of signalling pathways. Here, we develop a basic model of pathway coupling - the sharing of one component between processes. In its most basic form, the coupling of processes and signalling can be studied via a simplified ordinary differential equation model, which involves the interaction of three species A, B and X.

Get Price2020-9-4 · Historical Views of Coupling. The idea that association among different barriers to gene flow is key to the speciation process is an old one: it underlies the notion of coadapted gene complexes evolving during allopatric speciation (Mayr 1963), and in the context of divergence with gene flow, early theory emphasized the importance of the evolution of linkage disequilibrium (LD) among barrier ...
Get Price2021-6-10 · Excitation-contraction coupling. Although the term excitation-contraction coupling confuses or scares some students, it comes down to this: for a skeletal muscle fiber to contract, its membrane must first be “excited”—in other words, it must be stimulated to fire an action potential. The muscle fiber action potential, which sweeps along the sarcolemma as a wave, is “coupled” to the ...
Get Price2008-12-16 · Auxin levels rise due to the effect of cell-shape changes on auxin transport dynamics, with the extent of the increase depending on the degree of curvature ( Protocol S1: Figure S9).
