Glucose transporters are a wide group of membrane proteins that facilitate the transport of glucose across the plasma membrane, a process known as facilitated diffusion. Because glucose is a vital source of energy for all life, these transporters are present in all phyla .
Glucose uptake is the process by which glucose molecules are transported from the bloodstream into cells through specialized membrane proteins called glucose transporters, primarily via facilitated diffusion or active transport mechanisms: [1]

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.
Glucose transporter type 4 (GLUT4), also known as solute carrier family 2, facilitated glucose transporter member 4, is a protein encoded, in humans, by the SLC2A4 gene. GLUT4 is the insulin -regulated glucose transporter found primarily in adipose tissues and striated muscle (skeletal and cardiac).
The mannose PTS in E. coli has the same overall structure as the B. subtilis glucose PTS, i.e. the IIABC domains are fused into one protein. In the process of glucose PTS transport specific of enteric bacteria, PEP transfers its phosphoryl to a histidine residue on EI. EI in turn transfers the phosphate to HPr.
Cells also contain anion antiporters such as the Band 3 (or AE1) anion transport protein. This cotransporter is an important integral protein in mammalian erythrocytes and moves chloride ion and bicarbonate ion in a one-to-one ratio across the plasma membrane based only on the concentration gradient of the two ions.
