Glucose transport is driven by a sodium gradient across the apical cell Facilitated diffusion utilizes a carrier protein to achieve transport at rates greater than 


though glucose transport via the passive mechanism is bidirectional, net transport always occurs in the direc- tion of high to low sugar concentration; and 2) transport

Some molecules and ions such as glucose, sodium ions, and chloride ions are unable to pass through the phospholipid bilayer of cell membranes. Facilitated diffusion of ions takes place through proteins, or assemblies of proteins, embedded in the plasma membrane. These transmembrane proteins form a water-filled channel through which the ion can pass down its concentration gradient. The transmembrane channels that permit facilitated diffusion can be opened or closed. 2010-04-07 · Numerical results indicate that the most crucial factor in determining the fetal glucose concentration is the facilitated diffusion process at the basal membrane or, more specifically: the permeability of the basal membrane and the density of the transporter GLUT1 on its faces. Se hela listan på This difference was attributed to the presence of a low-affinity facilitated-diffusion glucose transporter identified in DSMZ 10140 but lacking in RB 4825.

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 transporter facilitated diffusion

There are over 10 different types of glucose transporters; however, the most significant for study are GLUT1-4. GLUT1 and GLUT3 are located in the plasma membrane of cells throughout the body, as they are responsible for maintaining a basal rate of glucose uptake.

Glucose transport across the placenta occurs through facilitated diffusion, aided by specific glucose transporters. The GLUT1 glucose transporter, present on both microvilli and basal membranes of the syncytial barrier, is the primary isoform involved in the transplacental movement of glucose, and is the rate-limiting step.
