Question
Three types of connective tissue fibers produced by fibroblasts and included in the extracellular matrix are ______.Multiple choice question.Myosin, tropomyosin, and troponinactin filaments, collagen fibers, and elastic fibersmicrotubules, microfilaments, and intermediate filamentscollagen fibers, elastic fibers, and reticular fibers
Solution
Para responder a la pregunta, primero debemos identificar los tipos de fibras de tejido conectivo que son producidas por los fibroblastos y que se encuentran en la matriz extracelular.
-
Myosin, tropomyosin, and troponin: Estas son proteínas asociadas con la contracción muscular, no con las fibras de tejido conectivo en la matriz extracelular.
-
Actin filaments, collagen fibers, and elastic fibers: Los filamentos de actina son componentes del citoesqueleto celular, no de la matriz extracelular.
-
Microtubules, microfilaments, and intermediate filaments: Estos son componentes del citoesqueleto celular, no de la matriz extracelular.
-
Collagen fibers, elastic fibers, and reticular fibers: Estas son las fibras producidas por los fibroblastos y que se encuentran en la matriz extracelular.
Por lo tanto, la respuesta correcta es: collagen fibers, elastic fibers, and reticular fibers.
