Across
  1. 4. Proteins that form pores in the membrane, allowing small molecules to pass via passive diffusion; ion-selective.
  2. 5. Membrane proteins that anchor cells to their surroundings by linking to the cytoskeleton and extracellular matrix.
  3. 6. Proteins that selectively allow charged and polar molecules to cross the membrane.
  4. 8. Integral membrane proteins that span the entire membrane.
  5. 9. Membrane proteins that use ATP energy to actively pump ions through the membrane.
  6. 10. A network of fibers within the cell that helps maintain its shape and is involved in movement.
Down
  1. 1. Membrane proteins with a hydrophobic region embedded within the hydrophobic core of the membrane.
  2. 2. Transmembrane proteins that bind to specific molecules in the extracellular matrix, triggering cellular responses.
  3. 3. Proteins that "drag" molecules through the membrane by hiding them in a cleft in the protein.
  4. 7. Membrane proteins that are not embedded in the lipid bilayer and attach to integral proteins or the hydrophilic heads of membrane lipids.
