What membrane molecule is responsible for aiding passage of polar molecules into and out of the cell?

            AS we know that the composition of plasma membrane is solely composed of phospholipids and protein molecules. lipid bilayer made up of phospholipid acts as differential permeable membrane because it allow only the transport of non polar molecules. however, there are some proteins known as carrier proteins that help in the transport of polar molecules through facilitated diffusion.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
