Across
- 4. A secreted molecules that influences cells near where it is secreted
- 5. A type of intercellular junction between animal cells that prevents the leakage of material through the space between cells
- 8. A transmembrane protein channel that opens or closes in response to a particular stimulus.
- 10. A protein loosely bound to the surface of a membrane or to part of an integral protein and not embedded in the lipid bilayer.
- 12. The meshwork surrounding animal cells, consisting of glycoproteins, polysaccharides, and proteoglycans synthesized and secreted by the cells
Down
- 1. A type of intercellular junction in animal cells, consisting of proteins surrounding a pore that allows the passage of materials between cells.
- 2. A component of the cytoskeleton that includes filaments intermediate in size between microtubules and microfilaments
- 3. A hollow rod composed of tubulin proteins that makes up part of the cytoskeleton in all eukaryotic cells and is found in cilia and flagella
- 6. A transmembrane protein with hydrophobic regions that extend into and often completely span the hydrophobic interior of the membrane and with hydrophilic regions in contact with the aqueous solution on one or both sides of the membrane (or lining the channel in the case of a channel protein).
- 7. A cable composed of actin proteins in the cytoplasm of almost every eukaryotic cell, making up part of the cytoskeleton and acting alone or with myosin
- 9. A type of intercellular junction in animal cells that function as a rivet, fastening cells together
- 11. An open channel through the cell wall that connects the cytoplasm of adjacent plant cells, allowing water, small solutes and some larger molecules to pass between the cells.
