Which cytoskeletal component is most directly involved in generating protrusive structures like lamellipodia and filopodia during cell migration?
Show answer and explanation
Correct answer: Actin (microfilaments)
Actin filaments assemble at the leading edge of motile cells to form lamellipodia and filopodia, generating protrusive force needed for cell migration.
