Cytochalasin D inhibits actin polymerization, which is crucial for processes like amoeboid movement, formation of cleavage furrows, contraction of muscle fibers, and extension of pseudopodia, all of which rely on actin filaments. However, vesicle movement within cells primarily depends on microtubules and motor proteins (like kinesin and dynein), not on actin filaments, so it can still occur in the presence of cytochalasin D.
