Show transcribed image text Which of the following acts as a motor to move along microtubules towards the positive (+) end? A. Kinesins B. Dyneins C. Mysosin D. Vimentin E. All of the above Intermediate filaments function in A. cell motility. B. providing mechanical strength for cells. C. nuclear pore structure. D. All of the above How does tropomyosin act to regulate muscle contraction? A. Causes myosin heads to cleave ATP B. Forms myosin thick filaments C. Releases Ca^2+ ions D. During contraction, moves along actin filament by binding to successive actin molecules of actin filament E. Blocks the myosin binding sites in the actin monomers of the actin filaments unless Ca^2+ ions are present
