59392. OpenStax. La membrana plasmática, que también se llama membrana celular, tiene muchas funciones, pero la más básica es definir los bordes de la célula y mantener la célula funcional. La membrana plasmática es selectivamente permeable.
Su función principal es definir lo que está dentro (el espacio intracelular) y lo que está fuera (el espacio extracelular). También regula lo que entra o sale de la célula, lo que se llama permeabilidad selectiva. La membrana celular está formada básicamente por una bicapa de moléculas de fosfolípidos.
19 de oct. de 2020 · The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell. It separates the cytoplasm (the contents of the cell) from the external environment. It is a feature of all cells, both prokaryotic and eukaryotic. a 3D diagram of the cell membrane Function of the Cell Membrane
Key terms. Structure and function of the cell membrane. The cell membrane is semipermeable (or selectively permeable). It is made of a phospholipid bilayer, along with other various lipids, proteins, and carbohydrates.
The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).
Hace 4 días · Cell membrane, thin membrane that surrounds every living cell. The cell membrane functions as a barrier, keeping cell constituents in and unwanted substances out, and as a gate, allowing transport into the cell of essential nutrients and movement from the cell of waste products.
(A) The plasma membrane of a cell is a bilayer of glycerophospholipid molecules. (B) A single glycerophospholipid molecule is composed of two major regions: a hydrophilic head (green) and...
