1.4 Membrane Transport - Coggle Diagram

- - - - From an area of high concentration to low concentration.
      - passive movement of particles
    - - The passive movement of water molecule
      - From an area of low concentration to high concentration.
    - - move across protein channels
        
        membrane protein changes its shape
    - - Temperature – molecules diffuse faster if the temperature is higher.
      - Surface area of membrane – an increase in surface area allows more molecules to diffuse.
      - Size of particles – smaller molecules diffuse faster than larger ones.
      - Concentration gradient of diffusing particles – the bigger the gradient the faster the diffusion.
- - - - water moves by osmosis out of the cell, so the cell shrinks
  - - - the concentration of solutes is greater inside the cell than outside of it, so the cell gains water through osmosis and swells up.
- - - - the absorption of solids (‘cell eating’)
    - - taking in of liquid substances by cells (‘cell drinking’)
  - - - any undigested remains of the microbe that are not useful to the cell are excreted outside the cell
    - - Proteins synthesized by ribosomes on rough endoplasmic reticulum are first passed to the Golgi apparatus via vesicles, before being released in vesicles that in turn fuse with the plasma membrane for secretion outside the cell.
