    Question

    ________ are only one of several molecular "machines" that cells use to perform mechanical tasks.

    Hint:

    Motor proteins perform the mechanical functions

    The correct answer is: Motor proteins

      • Motor proteins are the class of molecular motors that cells use to perform mechanical functions 
      • These motor proteins can move along the cytoplasm of animal cells 
      • They are involved in active transport of most proteins and vehicles in the cytoplasm
