Question

Compare and contrast facilitated diffusion, active
transport, and secondary active transport.

Expert Solution
Step 1

The membrane transport system is the transport system by which many molecules penetrate into and out of cells across the cell membrane. 

Step 2

Active transport is an active process. Thus, it requires energy. Whereas facilitated diffusion is a passive process and does not require energy. Active transport is used to transport molecules against their concentration gradient.
