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.
Phases Â· Phase transition Â· QCP. An exciton is a bound state of an electron and an electron hole which are attracted to each other by the electrostatic Coulomb force. It is an electrically neutral quasiparticle that exists in insulators, semiconductors and in some liquids. The exciton is regarded as an elementary excitation of condensed matter that can transport energy without transporting net electric charge. An exciton can form when a photon is absorbed by a semiconductor. This excites an electron from the valence band into t
