When Listeria monocytogenes invades a eucaryotic cell, it secretes the ActA protein that A) polymerizes actin filaments, causing the bacterium to move through the cytoplasm. B) depolymerizes microfilaments, allowing the bacterium to move more easily in the cytoplasm. C) degrades the cytoskeleton, allowing the bacterium to travel through the plasma membrane to adjacent cells. D) attaches to microtubules, allowing the bacterium to move along the fibers
