Carrier Proteins
cell membrane
Receptor proteins.
They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion. in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.
To recognize antigens.

"Pick Up" Proteins Is Active Transort!

It is niether. Its is passive actually. http://www.mansfield.ohio-state.edu/~sabedon/campbl08.htm #38. under Endocytosis, which is active passport, includes the example of Receptor-Mediated Endocytosis.

Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
by active and passive transport via cell membrane proteins
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
