question 53

Essay

Cytochalasin is a drug that caps actin filament plus ends, thus preventing actin polymerization.Phalloidin is a drug that binds to and stabilizes actin filaments, preventing actin depolymerization.Even though these drugs have opposite effects on actin polymerization, the addition of either of these drugs instantaneously freezes the cell movements that depends on actin filaments.Explain why drugs that have opposite effects on actin filaments can have a similar effect on cell movements.
