What forms the outer boundary of the cell and allow only certain materials into and out of the cell?
Proteins of many, many specific forms make up these highly varied and specific gateways.
Within the nuclear [bi-Lipid layer membranous] envelope, the most we have to deal with is the eight-membered Nuclear Pore. However, within the external Membranes of Cells the number of Bio-Channels (along with the even greater number of 'Incoming Signal Receptors' - which are also known as 'trans-membrane transducers') are all but too numerous to List.
