The reduced folate carrier protein (RFC) is a transmembrane protein responsible for the transport of folate, or vitamin B9, into cells. It uses the large gradient of organic phosphate to move folate into the cell against its concentration gradient.
Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell. Active transport is the movement of a substance across a membrane against its concentration gradient. This ...
This action creates a sodium concentration gradient across the cell membrane, with a lower concentration inside the cell compared to both the blood and the tubular lumen. [3] SGLT proteins utilize this sodium gradient to transport glucose across the apical membrane into the cell, even against the glucose concentration gradient.
An electrochemical gradient or concentration gradient is a difference in concentration of a chemical molecule or ion in two separate areas. [6] At equilibrium the concentrations of the ion in both areas will be equal, so if there is a difference in concentration the ions will seek to flow "down" the concentration gradient or from a high ...
Permitting one ion or molecule to move down an electrochemical gradient, but possibly against the concentration gradient where it is more concentrated to that where it is less concentrated, increases entropy and can serve as a source of energy for metabolism (e.g. in ATP synthase). The energy derived from the pumping of protons across a cell ...
Method of glucose uptake differs throughout tissues depending on two factors; the metabolic needs of the tissue and availability of glucose.The two ways in which glucose uptake can take place are facilitated diffusion (a passive process) and secondary active transport (an active process which on the ion-gradient which is established through the hydrolysis of ATP, known as primary active ...
