Q: The electrochemical potential across a membrane determines the tendency of an ion to do what?


Read this paragraph and choose the correct option from the provided answers:

The electrochemical potential across a membrane determines the tendency of an ion to cross the membrane. The membrane may be that of a cell or organelle or other sub cellular compartment. The electrochemical potential arises from three factors:.

 Choices:

- attach to the membrane

- move away from the membrane

- destroy the membrane

- cross the membrane


A:
cross the membrane
