Thus in a mixture of actin, profilin, and nucleotides (ADP and ATP), actin will polymerize to a certain extent, which may be estimated by the law of mass action.
Así, nunha mestura de actina, profilina e nucleótidos (ADP e ATP), a actina vaise polimerizar en certa medida, o cal pode estimarse pola lei de acción de masas.
