5 Written Questions

1. location: make up the cytoskeleton. structure: made of actin protein, polymers that are helically intertwined into filaments. function: contribute to internal architecture of cell, important component of cytoskeleton.
2. location: between cell membrane and nucleus. structure: composed of cytosol and cytoskeleton. funtion: cytosol bathes organelles, cytoskeleton maintains shape of cell and helps organelles move.
