Across
  1. 4. "Glyco-" This biomolecule on the cell membrane allows the cell to recognize other cells.
  2. 6. The concentration of water is equal on both sides of the membrane.
  3. 8. This type of transport requires no energy and moves molecules from high to low concentration
  4. 10. This is a type of transmembrane protein that forms hydrophilic tunnels across the membrane so molecules can pass through by diffusion.
  5. 11. Cell eating; a type of endocytosis.
  6. 13. Active transport moves molecules _________ the concentration gradient, from low to high concentration.
  7. 14. These proteins need ATP to move molecules from areas of low to high concentration.
  8. 16. The receptors in receptor-mediated endocytosis are _________ that are used to capture a specific target molecule.
  9. 18. This type of transport can be broken down into 3 categories and involves the movement of particles into the cell by enclosing them in a vesicle made of membrane.
Down
  1. 1. This type of solution has a higher solute concentration inside the cell and causes water to flow into the cell, making it swell.
  2. 2. A type of bulk transport where molecules are transported out of the cell in vesicles.
  3. 3. Facilitated diffusion is a type of passive transport that requires the help of membrane _________ to move large, polar, and/or charged molecules.
  4. 5. A type of endocytosis where the cell takes in extracellular fluid; cell drinking.
  5. 7. This type of transport requires energy and moves large particles or large quantities of smaller particles across the membrane in vesicles (globes of membrane).
  6. 9. This primary energy carrier in living things releases energy when a bond is broken and is used in ACTIVE transport.
  7. 12. This is the type of diffusion where small, nonpolar/hydrophobic molecules like O2 and CO2 can pass right through the membrane
  8. 13. These are channel proteins that allow water to move quickly across the membrane.
  9. 15. This type of transport involves the movement of water from an area of high to low water concentration.
  10. 17. The hydrophilic ______ of a phospholipid, which make up the cell membrane, face outward, contacting the aqueous (watery) fluid both inside and outside the cell.
