1) Three types of protein fibers make up the cytoskeleton. Which protein type is mismatched to its function? intermediate filaments: provide strength to the cell microfilaments: help with cell contraction microtubules: provide tracks on which organelles can move along microfilaments: help with cell division intermediate filaments: help pull chromosomes apart during cell division 2) What is the common property of competitive and noncompetitive enzyme inhibitors? They make it impossible for the substrate to bind to the active site. They speed up metabolic reactions. They bind to the enzyme's active site. They prevent the enzyme from doing its job.

Classify each characteristic based on whether it describes actin filaments, intermediate filaments, and/or microtubules. Some characteristics may apply to more than one category. Primarily associated with movement Involved in cell division Protein composition varies from cell to cell Take part in formation of cell-to-cell junctions Support the plasma membrane Act as tracks along which organelles can move Short, cylindrical structures composed of 13 rows of tubulin Colchicine binds these fibers to block cell division The proteins of this fiber interact with myosin during muscle contraction Support the nuclear envelope Actin filaments Intermediate filaments Microtubules

Fibers of the cytoskeleton Match each function with the correct cytoskeletal structure Used to move cells Za 6 Actin Intermediate Filaments Used to move vesicles within cells Microtubules Cables of staggered protein tetramers Strong structural protein within cells Stable and usually do not break down Responsible for the arrangement of chromosomes during cell division Made of tubulin protein subunits Also called microfilaments Reset
