In plants, sucrose transport is distributed throughout the plant by the proton-pump where the pump creates a gradient of protons so that there are many more on one side of the membrane than the other. As the protons diffuse back across the membrane, the free energy liberated by this diffusion is used to co-transport sucrose. In mammals, glucose ...
The transport of glucose across the proximal tubule cell membrane involves a complex process of secondary active transport (also known as co-transport). [3] This process begins with the Na + /K + ATPase on the basolateral membrane. This enzyme uses ATP to pump 3 sodium ions out of the cell into the blood while bringing 2 potassium ions into the ...
This is an electrogenic process with an apparent stoichiometry of 3 bicarbonate ions per sodium ion. Sodium bicarbonate co-transport is involved in bicarbonate secretion/absorption and intracellular pH regulation. Romero and Boron (1999) reviewed NBCs.
Coenzyme A (CoA, SHCoA, CoASH) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle.All genomes sequenced to date encode enzymes that use coenzyme A as a substrate, and around 4% of cellular enzymes use it (or a thioester) as a substrate.
A symporter is an integral membrane protein that is involved in the transport of two (or more) different molecules across the cell membrane in the same direction. The symporter works in the plasma membrane and molecules are transported across the cell membrane at the same time, and is, therefore, a type of cotransporter .
The anion exchanger family (TC# 2.A.31, also named bicarbonate transporter family) is a member of the large APC superfamily of secondary carriers. [1] Members of the AE family are generally responsible for the transport of anions across cellular barriers, although their functions may vary.

There are several known sodium-dependent phosphate transporters found in humans. For example, the protein 2A is encoded by the solute carrier family 34, member 1 (SLC34A1) gene [7] and facilitates uptake of phosphate for normal cellular functions including cellular metabolism, signal transduction, and nucleic acid and lipid synthesis.
