Flashcards in  class3 Zaidi-transport Thru Membranes Deck (77)
Ex of antiporter
Sodium calcium exchanger
Ex of symporter
Ex of uniporter
Mitochondrial Ca+ transporter
Uses a proton gradient generated by oxidation of fuel molecules to drive lactose and other sugars against [ ] gradient
Is a symporter
Steps of lactose permease:
5- H+ in
Polytopic membrane proteins are often:
What 2nd structure are proteins that make up polytopic transport proteins in membrane
Sodium pump _____ and K+ pumps in ______
uses ATP to change conformation for action to occur
If + ∆G what type of transport
If -∆G what transport:
Passive: simple or facilitated diffusion
Why is P type called P type ATPase?
P=phosphate covalently bonded to protein during process that req's energy.
Ex: SERCA Na+/K+ pump / PMCA
Where does (Pi) phosphate bind on P type ATPase?
Inhibit the dephosphorylation of E2P state of the Na+/K+ pump
ATP binds to this point________ causing the active for of PMCA
btw 4 and 5 transmembrane domains
