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...

In cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of...

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

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

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...

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

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

of membranes that forms a single functional and developmental unit, either being connected directly, or exchanging material through vesicle transport. Importantly...

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...

linked transporters (SGLTs) are responsible for the active transport of glucose across cell membranes. SGLT1 and SGLT2 are the most well-studied members of...

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

dopamine transporter (DAT, also sodium-dependent dopamine transporter) is a membrane-spanning protein coded for in humans by the SLC6A3 gene (also known as...

Excitatory 5-HT3 Ligand-gated Na+ and K+ cation channel. Depolarizing plasma membrane. Excitatory 5-HT4 Gs-protein coupled. Increasing cellular levels of cAMP...

A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment...

cell membrane by passive means. Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport. Exocytosis...

this process are as follows: The Na+/I− symporter transports two sodium ions across the basement membrane of the follicular cells along with an iodide ion...

transporters are a wide group of membrane proteins that facilitate the transport of glucose across the plasma membrane, a process known as facilitated...

A vesicular transport protein, or vesicular transporter, is a membrane protein that regulates or facilitates the movement of specific molecules across...

The relatively static membrane potential of quiescent cells is called the resting membrane potential (or resting voltage), as opposed to the specific dynamic...

Membrane technology covers all engineering approaches for the transport of substances between two fractions with the help of semi-permeable membranes...

Reverse transport, or transporter reversal, is a phenomenon in which the substrates of a membrane transport protein are moved in the opposite direction...

membrane. Only special membrane proteins like ion channels can sometimes allow ions to move across the membrane (see also: Membrane transport). In the chemiosmotic...
