Biography and career. Satterfield was born Louis Edward in Shaw, Mississippi, a city in Bolivar and Sunflower counties, Mississippi, in the Mississippi Delta region, on April 3, 1937.
Excitation-contraction coupling (ECC) is the process whereby an action potential triggers a myocyte to contract.When a myocyte is depolarized by an action potential, calcium ions enter the cell during phase 2 of the action potential through L-type calcium channels located on the sarcolemma.hen calcium binds to the TN-C, this induces a conformational change in the regulatory complex such that troponin-I (TN-I) exposes a site on the actin molecule that is able to bind to the myosin ATPase located on the myosin head.
The intensity ratio of the first two lines signals the number of protons involved in the coupling: 1:1 means there is only one proton, 1:2 means that there is a triplet splitting (2 protons), etc. Be especially careful to keep track of intensities when you take out triplets (1:2:1) or quartets (1:3:3:1).here are two distinct types of magnetic interaction (coupling) between nuclei (A and X) with a non-zero spin-the direct interaction (dipole-dipole coupling: D) and the indirect or scalar coupling (spin-spin splitting: J).
