A&P cell transport
| Question | Answer |
|---|---|
| Integral proteins | ion channels, receptors, transporters |
| Peripheral proteins | surface markers, membrane bound, enzymes |
| transporters | GluT-glucose transporter SGLT- sodium-dependent glucose transporter 3 Na+(out)/2 K+(in) Pump |
| passive transport | no energy needed, down the concentration gradient (high conc. to low conc.) |
| simple diffusion | passive transport, small & nonpolar solutes |
| facilitated diffusion | passive transport, needs a transporter (ex. GluT) |
| osmosis | passive transport, water movement (no solute movement), water moves high to low |
| active tranport | move against concentration gradient (low to high), needs ATP |
| primary active transport | direct uses of ATP (ex. Na+/K+ Pump) |
| secondary active transport | indirect use of ATP, coupled to Primary Active Transport |
