Step 1
First, the amoeba extends a part of its body, called a pseudopod, in the direction it wants to move. This is done by the growth of actin filaments to form bulges in the plasma membrane. Show more…

Movement of amoebae across a surface requires which of the following activities by components of the cytoskeleton? - assembly of actin filaments to form bulges in the plasma membrane - localized contractions driven by myosin and microtubules - assembly of microtubule extensions that vesicles can follow in the direction of movement - reinforcement of the pseudopod with intermediate filaments

Cell motility has been described as being like the motion of tank treads. At the leading edge, actin filaments form rapidly into bundles and networks that make protrusions and move the cell forward. At the rear, cell attachments are broken and the tail end of the cell is brought forward. What provides the traction for moving cells? How does cell-body translocation happen? How are cell attachments released as cells move forward?
