Transpor molekul melintasi membran

• Transport pasif (Difusi)

• Transpor aktif

• kotranspor

• Osmosis merupakan transpor pasif air

-keseimbangan air pada sel tanpa dinding

- Keseimbangan air pada sel berdinding

Protein transpor

• Difusi terfasilitasi

• Protein transpor memiliki banyak sifat enzim

• Saluran bergerbang:

-voltaged-gated channels

-ligand-gated channels

• Transpor aktif merupakan pemompaan zat terlarut melawan gradiennya

• Potensial membran

• Pompa elektrogenik

• Gradien elektrokimiawi

• Pompa proton, pompa Na/K
