Answer:
Explanation:
Actin filaments are linear chain of globular actin (G-actin) subunits.
Actin filaments occur as microfilaments in the cytoskeleton inside the cell membrane, which are part of the contractile apparatus in muscle and non-muscle cells and various other type of cells.
Actin filaments are particularly abundant beneath the plasma membrane, they form a network that provides mechanical support, they determines cell shape, enabling cells to migrate, engulf particles, and divide.
