Thus, the hydrophilic heads of the glycerophospholipids in a cell's plasma membrane face both the water-based cytoplasm and the exterior of the cell. Altogether, lipids account for about half the ...

We are taught that plasma membranes are a typical lipid ... The answer to this problem is to enclose the cytoplasm with a membrane that prevents the free movement of molecules.

The mRNA then exits the nucleus, and translation occurs in the cell’s cytoplasm. Prokaryotes can be split into ... whose cells have a nucleus and other organelles enclosed by a plasma membrane (Figure ...
