secondary active transport

These co-transporters are an example of secondary active transport.

Secondary active transport involves the use of an electrochemical gradient.

This increases the reabsorption of divalent cations by secondary active transport.

Secondary active transport, however, makes use of potential energy, which are usually derived through exploitation of an electrochemical gradient.

There are two forms of active transport, primary active transport and secondary active transport.

This happens because of the sodium gradient between the tubule and the cell and therefore provides a secondary active transport of glucose.

The secondary active transport of glucose in the kidney is Na linked; therefore an Na gradient must be established.

Secondary active transport is the type of active transport used, meaning that VMAT1 is an antiporter.

GSH, ion-coupled transport, active transport, symport, secondary active transport, membrane transport.

Ions and minerals that need to be saved in the body are reabsorbed into the peritubular capillaries through active transport, secondary active transport, or transcytosis.

Epithelial cells use primary and secondary active transport, often in conjunction with passive diffusion through ion channels, to produce transcellular transport across epithelial tissues.

In secondary active transport, one species of solute moves along its electrochemical gradient, allowing a different species to move against its own electrochemical gradient.

It works against the iodide concentration gradient and uses energy of sodium gradient (maintained by the sodium-potassium pump) and therefore acts by secondary active transport.

Proton-translocating ATPases have fundamental roles in energy conservation, secondary active transport, acidification of intracellular compartments, and cellular pH homeostasis.

Nucleoside transport processes comprise a diverse array that includes facilitated diffusion processes as well as concentrative, sodium-dependent, secondary active transport processes.

Where the hydrolysis of the energy provider is indirect as is the case in secondary active transport, use is made of the energy stored in an electrochemical gradient.

However, glucose, amino acids, inorganic phosphate, and some other solutes are reabsorbed via secondary active transport through cotransport channels driven by the sodium gradient out of the nephron.

This is a secondary active transport because the sodium gradient generated for the functioning of the sodium/calcium exchanger is created by the sodium/potassium pump which requires ATP.

Unlike channel proteins which only transport substances through membranes passively, carrier proteins can transport ions and molecules either passively through facilitated diffusion, or via secondary active transport.

The two ways in which glucose uptake can take place are facilitated diffusion (a passive process) and secondary active transport (an active process which indirectly requires the hydrolysis of ATP).

This type of transport is known as secondary active transport and is powered by the energy derived from the concentration gradient of the ions/molecules across the membrane the cotransporter protein is integrated within.

As the cotransport of glucose with sodium from the lumen does not directly require ATP hydrolysis but depends upon the action of the ATPase, this is described as secondary active transport.

Since NKCC proteins use sodium's gradient, their activity is indirectly dependent on ATP; for this reason, NKCC proteins are said to move solutes by way of secondary active transport.

An antiporter (also called exchanger or counter-transporter) is a cotransporter and integral membrane protein involved in secondary active transport of two or more different molecules or ions (i.e., solutes) across a phospholipid membrane such as the plasma membrane in opposite directions.

In secondary active transport, also known as coupled transport or co-transport, energy is used to transport molecules across a membrane; however, in contrast to primary active transport, there is no direct coupling of ATP; instead it relies upon the electrochemical potential difference created by pumping ions in/out of the cell.
