Detailed explanation-1: -Active transport is an active process and facilitated diffusion is a passive process. Both active transport and facilitated diffusion are selective as they allow only particular type of molecules to enter inside the cell. Both active transport and facilitated diffusion require membrane proteins.

Detailed explanation-2: -Active and passive transport regulate the entry and exit of ions and molecules in a cell. These processes allow only specific materials to cross spontaneously through the cell membrane.

Detailed explanation-3: -Transport proteins function in both active and passive transport to move molecules across the plasma membrane.

Detailed explanation-4: -In Active transport the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP (energy). In Passive transport, the molecules are moved within and across the cell membrane and thus transporting it through the concentration gradient, without using ATP (energy).

Detailed explanation-5: -For the most part, carrier proteins mediate active transport while channel proteins mediate passive transport. Carrier proteins create an opening in the lipid bilayer by undergoing a conformational change upon the binding of the molecule. Channel proteins form hydrophilic pores across the lipid bilayer.
