1. Membrane proteins facilitate the transport of ions as well as drugs and proteins.___,a family of cell
Integrins
2. The concentration gradients of various ions (Na+, K+, Ca2+, etc.) set up an ____ across the plasma
electropotential gradient
3. The Na+/K+ pump pumps 3 Na+ outside in exchange for 2K+ inside (against the gradient), thus generating
electrochemical gradient
4. The ion channels (Na+, K+, Ca2+, etc) are regulated membrane pores which open forless than a millisecond
electrical potential or ligands.
5. The inactive state of the ion channels allows the action potential to progress in only ____ and thus lead the
onedirection
6. The action of ionic channels and pumps are important for propagating ___and pathogen mediated signaling.
sensory signaling
7. uniport system
can only go one way
8. symport transport system
needs 2 different molecules to bind and then can go through
9. antiport transport system
needs molecule at both sides and switches
