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]
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 .
The method of glucose uptake varies across tissues based on two factors: the metabolic needs of the tissue and the availability of glucose. This uptake occurs through two mechanisms: Facilitated Diffusion - a passive process that relies on carrier proteins to transport glucose down a concentration gradient. [1]
Glucose in the body increases after food consumption. 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.

GLUT1 facilitates the transport of glucose across ...
There are two types of active transport, primary active transport and secondary active transport. [citation needed] Primary active transport uses adenosine triphosphate (ATP) to move specific molecules and solutes against its concentration gradient. Examples of molecules that follow this process are potassium K +, sodium Na +, and calcium Ca 2+.
Glucose transporters are integral membrane proteins that mediate the transport of glucose and structurally related substances across cellular membranes.Two families of glucose transporter have been identified: the facilitated diffusion glucose transporter family (GLUT family), also known as uniporters, and the sodium-dependent glucose transporter family (SGLT family), also known as ...
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 ...
