Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.

Intuitively, you probably believe that the rate of net diffusion or the flux of A across the membrane is directly proportional to the concentration gradient across the membrane.

It explores types of active transport, including primary and secondary; the Major Facilitator Superfamily (MFS) transporters, their structure, and roles; membrane ATPases, their classes, and physiological importance; the structure and function of ABC transporters; and the nuclear pore complex's transport mechanisms.
