Biological membranes include cell membranes (outer coverings of cells or organelles that allow passage of certain constituents); [2] nuclear membranes, which cover a cell nucleus; and tissue membranes, …

membrane, in biology, the thin layer that forms the outer boundary of a living cell or of an internal cell compartment. The outer boundary is the plasma membrane, and the compartments enclosed by …

There are many different kinds of membranes in a cell. Learn how they subdivide sections of a cell and how proteins in these membranes are gatekeepers for what goes in and what comes out.

In this chapter we consider the structure and organization of the two main constituents of biological membranes—the lipids and the membrane proteins. Although we focus mainly on the plasma …

Membranes is an international, peer-reviewed, open access journal covering the broad aspects of the science and technology of both biological and non-biological membranes, published monthly online …

Aug 3, 2025 · The endoplasmic reticulum and Golgi apparatus use membranes to synthesize and ship proteins and lipids. These variations show how the basic membrane architecture has been adapted …

16.3: Membrane Proteins Clearly, membrane proteins themselves have domains that keep membranes in or attached to the membrane, provide catalytic surfaces and allow interactions inside, across and …

Mucous membranes line the interface between the body cavities and the outside world, which include the digestive, respiratory, excretory, and reproductive tracts.

Plasma membranes enclose the borders of cells, but rather than being a static bag, they are dynamic and constantly in flux. The plasma membrane must be sufficiently flexible to allow certain cells, such …

The cell membrane is a dynamic structure composed of lipids, proteins, and carbohydrates.
