Homework Answers
Answer:
A) Symporter
Explanation: Symporter is the movement of two substances in the same direction
Antiporter is the movement of the two substances in opposite direction
Importer is the movement of a substance inside the cell while deporter is the movement of a substance outside.
Add Answer to:
During secondary active transport, the movement of one substance down its electrochemical gradient provides the force...

The Nat -k* pump uses the energy of Nat moving down its concentration gradient to pump k up its concentration gradient. Answers A-B A True B False Voltage-gated Na* channels exist in three distinct conformations in axons because Answers A-D A they assume an inactivated conformation shortly after opening, which ensures that the action potential cannot move backwards toward the cell body. B they change conformation when binding Nat and transporting it to the opposite side of the membrane before...
