Problem:
Dynein motor proteins use ATP energy to:
a) carry vesicles along a microtubule within a cell in a minus-to-plus direction.
b) carry vesicles along a microfilament within a cell in a minus-to-plus direction.
c) carry vesicles along a microtubule within a cell in a plus-to-minus direction.
d) carry vesicles along a microfilament within a cell in a plus-to-minus direction.
e) slide along microfilaments to contract muscle cells.
Could anyone help me please?
