Transport across membranes

1234567
Across
  1. 4. Proteins that change shape to move molecules across the membrane.
  2. 5. Increase surface area for transport protein insertion.
  3. 7. A type of diffusion that is the passive net movement of molecules from high to low concentration.
Down
  1. 1. Process to breakdown ATP to provide energy.
  2. 2. A type of diffusion that is the passive movement via protein channels/carriers, down a concentration gradient.
  3. 3. A type of transport that causes movement against a concentration gradient (low to high), requiring ATP and carrier proteins.
  4. 6. Net movement of water from higher to lower water potential across a partially permeable membrane.
