  2. Glucose transporter - Wikipedia

    en.wikipedia.org/wiki/Glucose_transporter

    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 .

  3. Facilitated diffusion - Wikipedia

    en.wikipedia.org/wiki/Facilitated_diffusion

    Since glucose is a large molecule, its diffusion across a membrane is difficult. [14] Hence, it diffuses across membranes through facilitated diffusion, down the concentration gradient. The carrier protein at the membrane binds to the glucose and alters its shape such that it can easily to be transported. [15]

  4. Uniporter - Wikipedia

    en.wikipedia.org/wiki/Uniporter

    The glucose transporter (GLUTs) is a type of uniporter responsible for the facilitated diffusion of glucose molecules across cell membranes. [9] Glucose is a vital energy source for most living cells, however, due to its large size, it cannot freely move through the cell membrane. [16]

  5. Glucose uptake - Wikipedia

    en.wikipedia.org/wiki/Glucose_uptake

    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 ...

  6. Insulin signal transduction pathway - Wikipedia

    en.wikipedia.org/wiki/Insulin_signal...

    This is primarily due to carbohydrate intake, but to a much lesser degree protein intake ()(). Depending on the tissue type, the glucose enters the cell through facilitated diffusion or active transport. In muscle and adipose tissue, glucose enters through GLUT 4 receptors via facilitated diffusion (). In brain, retina, kidney, RBC, placenta ...

  7. PEP group translocation - Wikipedia

    en.wikipedia.org/wiki/PEP_group_translocation

    The phosphoryl group on PEP is eventually transferred to the imported sugar via several proteins. The phosphoryl group is transferred to the Enzyme E I (EI), Histidine Protein (HPr, Heat-stable Protein) and Enzyme E II (EII) to a conserved histidine residue, whereas in the Enzyme E II B (EIIB) the phosphoryl group is usually transferred to a cysteine residue and rarely to a histidine.

  9. Symporter - Wikipedia

    en.wikipedia.org/wiki/Symporter

    The movement of the ion(s) across the membrane is facilitated diffusion, and is coupled with the active transport of the molecule(s). In symport, two molecule move in a 'similar direction' at the 'same time'. For example, the movement of glucose along with sodium ions. It exploits the uphill movement of other molecules from low to high ...
