Question

"active transport is when molecules diffuse from a higher concentration to a lower concentration. facilitated transport is when proteins that extend through the cell membrane provide a channel through which certain substances can diffuse more rapidly than by passive diffusion. the lipid bilayer opens up, allows the ions or molecules to enter the cell, and then closes. diffusion, or passive transport, is when molecules diffuse from a lower concentration to a higher concentration."

Answer 1

Active transport is the movement of molecules across a cell membrane from a region of their lower concentration
to a region of their higher concentration— against concentration gradient
Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a cell's
membrane via specific transmembrane integral proteins.
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration.
