Question

Vesicles, organelles, and chromosomes are all moved along cytoskeletal elements/proteins. What, below, is FALSE about these processes? Select one: a. Dynein, part of the kinetochore structure (what is this again?), moves towards the - pole of microtubules during metaphase. b. Myosin, the motor protein that works on actin microfilaments, requires ATP to move. This is how certain cells, like amoeba, move their plasma membranes/themselves through the environment. c. Kinesin moves towards the + end of microtubules; and, like almost all myosins and dyneins, requires ATP (a nucleotide) to power kinesin's movement. d. Both actin and tubulin bind to ATP and GTP, respectively. It is through the hydrolysis of these nucleotides, to their diphosphate form (like ADP/GDP), that microfilaments and microtubules can depolymerize more rapidly. e. All of the above are TRUE
