is the outer membrane of the cell. Plasma membrane and cell membrane are synonymous.
The lipid bilayer membrane that forms the boundary of a cell.
This holds the cell together. It keeps all the pieces, like the organelles, inside. The membrane also controls what goes in and out of the cell. It acts kind of like a crossing guard.
A delicate structure which encloses the cell, separating the contents of the cell from the surrounding environment.
The semi-porous outer membrane of a cell, found between the cytoplasm and the cell wall.
this membrane surrounds the cytoplasm of all cells. It is composed of a phospholipid bilayer with interspaced proteins.
The external, limiting lipid bilayer membrane of cells.
the semipermeable membrane that encloses the cytoplasm of a cell.
separates internal metabolic events from the external environment and controls the movement of materials into and out of the cell. It bounds the cell and encloses the nucleus and cytoplasm.
also called a cell membrane; a membrane composed of lipids, proteins, and phospholipids.
The membrane that surrounds the cell, regulating the entry and exit of molecules and ions. Every cell has a plasma membrane.
The membrane surrounding animal and plant cells.
a thin membrane around the cytoplasm of a cell; controls passage of substances in and out of the cell
The membrane that separates the contents of a cell from its outside environment; it consists of a double layer of phospholipids with embedded proteins.
A microscopic barrier associated with cells composed mainly of a phospholipid bilayer and protein. The outer plasma membrane of a cell is also called the cell membrane.
The outer lining of the cell that is responsible for regulation of the cell's internal environment.
the outer boundary of the cell comprised of 4-5 nm thick continuous sheet of lipid and protein molecules.
The phospholipid bilayer that surrounds a cell, forming a selectively-permeable barrier.
Membrane that surrounds a living cell.
outer membrane of cells composed of proteins and a phospholipid bi-layer that controls cellular traffic
the fatty layer surrounding the molecules of a cell.
Outer membrane of a cell, sometimes called the cell membrane. The term plasma membrane is used more frequently when discussing prokaryotes.
The outer membrane of a cell. Also called the cell membrane or cell wall.
This is the name given to the external membrane of a cell. It arises because certain cells (such as human red blood cells) are surrounded by plasma (which is the largest constituent of blood by volume). However, the term is now used in preference to cell membrane to refer to the outer membrane of any cell.
The membrane surrounding a cell.
All cells are surrounded by a plasma membrane surrounding the cytoplasm. The plasma membrane is composed of a lipid bilayer in which proteins are imbedded. Primer Small building blocks used to begin the synthesis of larger macromolecules Prosthetic group A metal ion or organic molecule (such as a vitamin derivative) that is bound to a protein and is essential for its activity. Pyridoxal phosphate PLP. A coenzyme formed from Vitamin B6 pyridoxine. Involved in enzyme reactions involving the transfer of amino groups.
The plasma membrane is the membrane which separates the inside of the red blood cells from the surrounding plasma.
membrana plasmatica] the cell membrane consisting of a bilayer of phospholipids and proteins.
The external cell membrane separating the interior and the exterior of the cell.
Also called cell membrane, the outer boundary of a cell
The physical barrier that surrounds the cytoplasm of all cells. It is composed of lipids, proteins and carbohydrates and is semi-permeable.
