Membrane channels that limit the movement of ions across the membrane are called:
A) leak channels
B) gated channels
C) exocytosis
D) endocytosis
E) leak channels and gated channels

Question

Quizplus · Accepted Answer

Gated channels limit the movement of ions across the membrane because they only open in response to specific signals or changes in the environment, whereas leak channels allow for the movement of ions to occur continuously without regulation. Therefore, gated channels serve as a way for the cell to control and regulate ion movement.
