Across
- 2. The transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane.
- 4. A nucleotide that is the primary source of energy in all living cells.
- 8. The engulfing and ingestion of bacteria or other foreign bodies by phagocytes.
- 9. A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
- 10. A molecule which represses or prevents another molecule from engaging in a reaction.
- 11. The movement of ions or molecules across a cell membrane in the direction opposite that of diffusion.
Down
- 1. Introduction of fluids into a cell by invagination of the cell membrane, followed by formation of vesicles within the cells.
- 3. The process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.
- 5. A process in which cell takes in materials from the outside by engulfing and fusing them with its plasma membrane.
- 6. A passage through a cell membrane used for communication between the outside and inside of a cell.
- 7. The movement of molecules from a high concentration to a low concentration.
