Question

Select all that apply for the sodium/potassium pump:

A- Two potassium ions are pumped out of the cell for every three sodium ions imported.

B- The pump is an ABC transporter that uses energy from ATP (one molecule) to pump sodium ions out of the cell and potassium ions into the cell.

C- The ions create an electric potential that causes the membrane to become polarized.

D- Two potassium ions are pumped into the cell for every three sodium ions exported.

E- The pump is an ABC transporter that uses energy from ATP (one molecule) to pump potassium ions out of the cell and sodium ions into the cell.

F- Two sodium ions are pumped into the cell for every three potassium ions exported.

Answer 1

Answer:

facilitated diffusion: The spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins.

membrane protein: Proteins that are attached to, or associated with the membrane of a cell or an organelle.
