In cellular biology, membrane transport refers to the collection of mechanisms that regulate the passage of solutes such as ions and small molecules through...

A membrane transport protein is a membrane protein involved in the movement of ions, small molecules, and macromolecules, such as another protein, across...

a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires...

Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy...

cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that...

membrane. Many of the enzymes in the electron transport chain are embedded within the membrane. The flow of electrons through the electron transport chain...

cell and monoamine oxidase (MAO) which is located in the mitochondrial membrane. Both enzymes require cofactors: COMT uses Mg2+ as a cofactor while MAO...

Biological membranes are selectively permeable, with the passage of molecules controlled by facilitated diffusion, passive transport or active transport regulated...

biological membrane. Carrier proteins are integral membrane proteins; that is, they exist within and span the membrane across which they transport substances...

Mitochondrial membrane transport proteins, also known as mitochondrial carrier proteins, are proteins which exist in the membranes of mitochondria. They...

Membrane potential (also transmembrane potential or membrane voltage) is the difference in electric potential between the interior and the exterior of...

Mediated transport refers to transport mediated by a membrane transport protein. Substances in the human body may be hydrophobic, electrophilic, contain...

also shown that transport rate and direction is totally dependent on the sodium gradient. Because of the tight coupling of the membrane potential and the...

endocytic membrane transport pathway originating from the trans Golgi network. Molecules or ligands internalized from the plasma membrane can follow...
