BIO 353 Exam 4 Study Guide Verified Questions And
Answers
define cytoskeleton ANS a network of filaments or tubes composed of protein subunits and
associated proteins
what are the three structural elements that constitute the cytoskeleton ANS intermediate
filaments, microtubules, and actin filaments
what are the primary functions of the cytoskeleton ANS cell motility, intracellular motility,
cytoplasmic order, and cell and tissue shape and support
what are the characteristics of intermediate filaments ANS tough ropelike fibers, do not bind
nucleotides, form structurally non-polar filaments, provides mechanical support to cells and tissues
what is the subunit of intermediate filaments ANS intermediate filament protein
are intermediate filaments structurally polar ANS no they are non-polar
do intermediate filaments have associated motor proteins ANS no, they are not directly
responsible for generating intra-cellular movements
what is the primary function of intermediate filaments ANS impart strength providing
mechanical support to cells and tissues
what are some examples of cytoskeletal structures that consist of intermediate filaments ANS
keratin filaments, neurofilaments, and nuclear lamins
what is keratin ANS epithelial cellular and tissue support
what is plectin ANS intermediate filament accessory protein
