Membrane-bound proteins that use metabolic energy to move ions across the plasma membrane are called
A)ion channels.
B)ion pumps.
C)peripheral protein pumps.
D)peripheral protein channels.
E)ion receptors.

Question

Quizplus · Accepted Answer

Membrane-bound proteins that use metabolic energy to move ions across the plasma membrane are called ion pumps. Ion channels allow ions to passively transport across the membrane without requiring energy, while ion receptors detect and bind to specific ions but do not move them actively. Peripheral protein pumps and channels are not commonly used terms in biology.
