Q

exozitosia

A
  • substantziak zelulatik kanporatu
  • xixku jariatzaile —mintza—-mintz plasmatikoarekin fusionatu
  • 2 mota
    1. jariaketa erregularra = zelularen berezko jariaketa ( prote jario –matrize estrazelularra osatzeko)
    2. estimulu bidezko jariaketa = zelulak seinale / estimulua behar ( neurotransmisore jariaketa)
