What is mediated transport?

A) The movement of molecules across a plasma membrane by means of a protein carrier
B) The movement of vesicles by intermediate filaments
C) The process of peptide synthesis on the surface of the ribosome
D) The ability of molecules to pass through the nuclear envelope

Mediated Transport

The movement of molecules across a cell membrane via specific carrier proteins, including both facilitated diffusion and active transport.

Protein Carrier

Molecules or substances that facilitate the transport of specific proteins across biological membranes or within the bloodstream.

Vesicles

Small, membrane-bound sacs within cells, used to transport and store substances within a cell or to export them outside the cell.
