Psychology Question:
A class of ion passes through an open channel:
Answer:
* a) When there is an electrochemical gradient for this ion across the membrane.
* b) Because ion pumps transport the ion across the membrane
* c) Because the selectivity filter conducts the ion through it.
* d) Because other ions of the same class link up together, and drag the ion with it.
* e) Because the voltage gates act as paddles, to sweep the ions through
