What is the diffusion problem how is it solved in eukaryotic cells?

Answer 1

The diffusion problem is based on relative concentrations in and outside of the cell and a lipid bilayer´s permeability to most of the ions essential to cell processes. It is solved by active transport and facilitated diffusion through protein channels and pumps both passively and through the use of ATP. .... I think ...

Answer 2

The diffusion problem refers to the challenge of moving molecules within the large and complex environment of eukaryotic cells. This is solved through various mechanisms, including the use of specific transport proteins to facilitate the movement of molecules across membranes, as well as organelles such as the endoplasmic reticulum and the Golgi apparatus which help to compartmentalize and streamline intracellular processes. Additionally, diffusion is also aided by the cytoskeletal network which provides structural support and facilitates the movement of molecules within the cell.
