The component that helps transfer substances across the membrane that I believe you are talking about, are the embedded protein channels. They help move larger particles across the cell membrane such as sodium because they are too large to move through the phospholipid bilayer.
a cell membrane controls movement of substances in and out of the cell.

A cell membrane surrounds all cells and controls the movement of substances.
The outer coating of a cell is called the cell membrane. It is a thin, flexible barrier that surrounds the cell and controls the movement of substances in and out of the cell.

Exocytosis is the process by which large substances are moved out of the cell. This involves the fusion of vesicles containing the substances with the cell membrane, releasing the substances outside the cell.
