Transport protein
A transport protein is a protein involved in facilitated diffusion. Changes in the conformation move the binding site to the opposite side of the protein.
Transport proteins are also used in active transport, which by definition does require an energy input.
A transport protein in the plasma membranes of a plant or animal cell that specifically facilitates the diffusion of water across the membrane (osmosis).
aqueous solution
(ay-kwee-us)
A solution in which water is the solvent.
The transport proteins integrated into the cell membrane are often highly selective about the chemicals they allow to cross.
channels Transport proteins that act as gates to control the movement of sodium and potassium ions across the plasma membrane of a nerve cell.
transportase --> transport protein
(Science: protein) A class of transmembrane protein that allows substances to cross plasma membranes far faster than would be possible by diffusion alone.
For example, most species lack glutathione peroxidase, glutathione reductase and respiratory-gas transport proteins and thus allow oxygen to diffuse directly into cells.
coli metabolic pathways to include signal-transduction pathways, transport proteins, regulation of gene expression, and tRNAs. Version5.0, released in June, contains detailed annotations of E.
The outer layer of the double membrane is much more permeable than the inner layer, which features a number of embedded membrane transport proteins.
carrier proteins - membrane transport protein that binds to a solute and transports it across the membrane by undergoing a series of conformational changes ...
ATP-ADP translocase An adenine nucleotide carrying a transport protein that carries ADP into the mitochondria and ATP out in a coupled fashion.
active transport A process that requires an expenditure of ATP energy to move molecules across a cell membrane; usually moved against the concentration gradient with the aid of specific transport proteins.
We used to think that it was a regulated process of how nucleic acids such as mRNAs moved out of the cell nucleus, and recently we've become more aware that there also is a regulated process by which cells transport proteins and nucleic acids into ...
