Clues

  • A kind of transport by which ions or molecules move along a concentration gradient. No energy is required. (7, 9)
  • A kind of transport where ions or molecules move against a concentration gradient. This process requires expenditure of energy and assistance of a carrier protein. ATP supplies energy for the carrier protein. (6, 9)
  • Allow glycolipids to form. Cell recognition and cell adhesion. (9, 8)
  • Bind with the molecule or ion, change shape and transport the particles across the membrane. (7, 8)
  • Cell recognition (12, 5)
  • Cell signaling and cell recognition (12)
  • Channel proteins: Passive transport. Carrier proteins: active transport. (9, 8)
  • Forms bilayer and impermeable barrier (12)
  • Span the membrane and have a specific shape to transport specific particles. (7, 8)
  • The fluid mosaic model describes the plasma membrane of animal cells. It's mosaic because it is embedded with proteins. It is fluid because it doesn't have a rigid structure. (5, 6, 5)
