1. The act of moving items from one location to another: The farmer planned the immediate transport of the wheat from the field to the storage place because of the expected stormy weather that was predicted to come.
2. The state or condition of rapture or strong, overwhelming emotions: Shareen felt the transport of the beautiful music from her radio as she was cleaning her apartment.

1. To carry or to convey something or people from one place to another one: Hundreds of refugees have been transported by means of trains and busses from their home country, which is still in the middle of a war, to another new peaceful country.
2. To put someone in a state of intense or uncontrollable emotion: Joe's girl friend was transported with great joy when he told her that he loved her and wanted to marry her. © ALL rights are reserved.

A process of biological oxidation in which electrons are transferred from a reduced substrate through a series of compounds to oxygen, the energy of the process being conserved by the formation of high-energy bonds in the form of adenosine triphosphate (an organic compound composed of adenine or base, the sugar ribose, and three phosphate groups) which serves as the major energy source within a cell to drive a number of biological processes; such as, photosynthesis, muscle contraction, and the synthesis of proteins.

1. A series of electron carriers which occurs within certain membranes; such as, the mitochondrial membrane, and produces energy for a cell.
2. The final common pathway of biological oxidation, the series of electron carriers in the inner mitochondrial membrane which pass electrons from reduced co-enzymes to molecular oxygen via sequential redox (oxidation-reduction) reactions coupled to proton transport, generating energy for biological processes.

The conversion of inorganic phosphate into pyrophosphate from a reaction powered by energy in a transmembrane gradient of ions generated by an electron transport chain.

It occurs in respiratory metabolism and in some types of fermentation.

1. A series of reduction-oxidation reactions, beginning with increased strength and ending in oxygen, which constitutes the final stage of aerobic respiration.

It is also involved in the light reaction of photosynthesis.

2. The components of the final sequence of reactions in biological oxidations.

They are composed of a series of oxidizing agents arranged in an order of increasing strength and terminating in oxygen.

The movement of charged, or uncharged, species across an energy-transducing membrane that does not result in a net transfer of charge.

1. The force that moves an ion across a membrane under a specific transport system energized by a concentration gradient within the ion itself, a gradient from another ion transport.
2. The movement of ions across energy-transducing cell membranes.

Transport can be active, passive or facilitated. Ions may travel by themselves (uniport), or as a group of two or more ions in the same (symport) or opposite (antiport) directions.

3. Movement of salts and other electrolytes in the form of ions from place to place within living systems.

Ion transport may occur by any of several different mechanisms; including, electrochemical diffusion, active-transport requiring energy, or bulk flow as in the flow of blood in the circulatory system of animals, or the transpiration stream in the xylem tissue of plants.

The best-known system for transporting ions actively is the sodium/potassium (Na/K) exchange pump, which occurs in plasma membranes of virtually all cells.
