In the Following Graph, the Magnitude of Concentration Difference Across

question 30

Short Answer

In the following graph, the magnitude of concentration difference across the nuclear pore complexes (NPCs) is plotted for four molecules (A to D) as a function of time, starting from an arbitrarily chosen initial concentration difference.

( ) A large protein that is being actively transported across the NPC
( ) A small water-soluble molecule
( ) A small protein composed of a few dozen residues
( ) A large protein that is NOT actively transported into or out of the nucleus
