BIO_181_Test_Bank_11)Pancake-shaped cells explores the environment – moving filopodia with receptors extend from cell surface all over cell and “sense” environment. (1 point) 2) Then in some area filopodia stop moving due to signal received (biochemical cascade changes cell in that area). (1 point) 3) That area restructures to extend large, lamellipodium that pushes out against the plasma membrane; the mechanism causing this is a new network of actin filaments. (1 point) 4) When l...
