What properties of IF monomers distinguish them from the monomers that make up M

Question

What properties of IF monomers distinguish them from the monomers that make up MFs or MTs? a) They bind to each other covalently. b) They are fibrous rather than globular proteins. c) They do not bind and hydrolyze nucleotides. d) They are numerous different types in different cell types. e) The are glycosylated. Which of the above differences makes IFs less dynamic structures than MFs or MTs. Polymerization/depolymerization of actin are essential for: (2) a) production of contractile forces in cells: b) movement of cilia and flagella c) crawling movements of cells over surfaces: d) protrusive movements of the cell surface e) maintaining the shape of a red blood cell During muscle contraction: (3) a) the myosin filaments shorten, bringing the actin filaments closer together. b) the thin filaments are bound to proteins in the Z discs. c) ATP hydrolysis by actin monomers drives the contraction.

Explanation / Answer
