CELL MEMBRANE-TRANSPORT PROTEINS

SUMMARY

DIVIDED BY: NUMBER OF SUBSTANCES
1. 3 broad types: uniports (transport only one substance), symports (transport multiple substances simultaneously), antiports (exchange substances)

DIVIDED BY: MECHANISM OF ACTION

2. Ion channels: volatage-gated, intracellular ligand-gated, extracellular ligand-gated, mechano-sensitive, simple-aqueous

3. Carriers: facilitated diffusion (moving molecules along their electro-chemical gradients, no energy required), active transport (moving molecules against their electro-chemical gradients, energy from ATP required)
