E)focal adhesion detachment

Question

Quizplus · Accepted Answer

Arp2/3-dependent actin polymerization is primarily responsible for the protrusion of lamellipodia at the leading edge of crawling cells. This process involves the branching and growth of actin filaments, pushing the plasma membrane forward.
