Cell membrane transport - Coggle Diagram
Cell membrane transport
Active transport
Requires energy
Molecules move
against
the concentration gradient.
Through membrane
Engulfing membrane (cytosis)
Endocytosis
Taken into the cell
Exocytosis
Taken out of the cell
Uses vescicles
Passive transport (difusion)
Doesn't require energy.
Simple diffusion
Small non-polar molecules (gases)
Pass through the phospholipid bilayer
Molecules move
with
the concentration gradient.
Facilitated diffusion
Big polar molecules (glucose)
Molecules pass through the protein channel
Osmosis
Movement of water through a semi-permeable membrane
Simple diffusion but for water
They use a transport/integral protein called
aquaporin
Regulates what goes in and out of the cell
Keeps homoestasis
