QUESTION 39 The following statement: Polymer provides tracks for dyneins applies to... actin/microfilaments tubulin/microtubules both cytoskeletal systems
QUESTION 35 What event occurs to divide the sister cells in two during cytokinesis? A. Constriction of the cell body by the sliding of myosin filaments on actin filaments. B. Contraction of the cell body by the shortening of actin and myosin filaments. C. Contraction of the cell body by shortening of the microtubules. D. Dissolving of the cytoplasm at the center of the cell body followed by polymerization of new actin filaments.
QUESTION 14 Which of the following statements is FALSE? A Microtubules will rapidly disassemble in response to a drop in the ATP concentration. B G-actin monomers and alpha-tubulin/beta-tubulin dimers assemble into filaments in their ATP-bound and GTP-bound forms, respectively. C Microtubules are stabilized by microtubule-binding proteins, such as Tau. D Actin-binding proteins allow F-actin to assemble in cells in many different ways. E Hydrolysis of ATP and GTP changes the conformation of the monomers once they are incorporated into actin filaments and microtubules, respectively.
QUESTION 15 Which of the following molecules is NOT a component of desmosomes? A Intermediate filaments B Actin C Plakoglobin D Desmoplakin E Desmocolin
QUESTION 12 What is most likely to occur in a cell when the levels of free GTP-bound tubulin subunits are very high in the cytoplasm? A The GTP cap on the end of the microtubules will shrink. B Microtubules will lengthen by adding tubulin subunits to their + ends. C The GTP-bound tubulin subunits will move into the nucleus. D Microtubules will undergo catastrophe and shorten. E Microtubules will lengthen by adding tubulin subunits to their - ends.
QUESTION 13 What is the mechanism by which microtubules can rapidly shrink, or undergo â catastrophe?â A At low levels of ATP, tubulin subunits are not added to the + end of the microtubule. B At low levels of GTP, beta-tubulin subunits at the + end of the microtubule hydrolyze GTP, undergo a conformational change, and destabilize the filament so that the filament starts to disassemble from the + end. C At low levels of GTP, tau proteins are phosphorylated and bind to the microtubule to destabilize the + end. D At high levels of GTP, tubulin subunits are more quickly added to the â end than to the + end of the microtubule, resulting in a shrinking + end of the microtubule. E At low levels of ATP, the microtubules rapidly disassemble since ADP-bound tubulin subunits are lost at both the + and â ends of the filament.
QUESTION 3 Which of the following statements regarding microtubules is FALSE? A Microtubules are polar. B Microtubules are inherently unstable and rapidly disassemble with low GTP concentrations. C Microtubule-binding proteins, such as Tau, always bind to microtubules to destabilize them. D Microtubules are composed of 13 protofilaments that are arranged into a hollow cylinder. E Microtubules are typically arranged in cells such that their plus (+) ends are directed towards the plasma membrane and their minus (-) ends are attached to the centrosomes.
QUESTION 9 Which of the following is/are a motor protein(s) that can carry vesicles along microtubules? A Dynein B Kinesin C Myosin D Tau E A and B
