Question

True or False?

Movement of Na⁺and K⁺through a Na⁺/K⁺–pump is a facilitated transport across a membrane

Movement of Na⁺and K⁺through a Na⁺/K⁺–transporter is an electrogenic antiporter process

Movement of Na⁺and K⁺through a Na⁺/K⁺–transporter is an active transport across a membrane

Answer 1

facilitated transport is the transport of molecules across the plasma membrane down the concentration gradient by a transporter protein.

Antiporter transports 2 molecules, in opposite directions.

electrogenic transport leads to the transport of a net charge across the membrane.

active transport is the transport of molecules across the plasma membrane against the concentration gradient, with the input of energy.

Na+/K+ antiporter transports 3 Na+ out and 2 K+ into the cell and with the input of ATP energy, it transports a net +1 charge to outside the cell.

Movement of Na+and K+through a Na+/K+–the pump is a facilitated transport across a membrane- false ( Na+/K+ pump is an active transporter)

Movement of Na+and K+through a Na+/K+–transporter is an electrogenic antiporter process- True ( Na+ and K+ are transported in opposite directions, and a net +1 charge is transported outside the cell, so this is electrogenic antiporter processes)

Movement of Na+and K+through a Na+/K+–transporter is an active transport across a membrane- True (Na+/K+ antiporter transports 3 Na+ out and 2 K+ into the cell and with the input of ATP energy, it transports a net +1 charge to outside the cell.)
