In passive transport across a membrane, when two different molecules move in the opposite direction and independent of each other, it is called ___________.
In passive transport across a membrane, when two different molecules move in the opposite direction and independent of each other, it is called ___________.

Solution:

Antiport

Antiport is a type of passive transport across a membrane in which two protein molecules travel in opposite directions and independently of one another.

Antiport is the opposite-direction passage of ions or molecules through the same transporter protein. This is a sort of diffusion that is aided.
