TRUE
|
|
|
FALSE
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Mirofilaments and microtubles serve as tracks for movement of motor proteins, which use energy in the form of ATP to “walk along” these cytoskeletal filaments. (Intermediate filaments are not associated with motor proteins.)
Detailed explanation-2: -Myosin is one superfamily of cytoskeletal motors, walking along the F-actin filaments. Kinesin and Dynein are both microtubule motors, walking towards microtubule’s plus-end and minus-end directions respectively.
