What tissue takes up the most glucose?

Skeletal muscle is where glucose uptake is quantitatively the most important. It is the bulk of insulin-sensitive tissue and the primary site of glucose uptake during exercise.

Where is glucose most absorbed?

Glucose is absorbed in small intestine by absorptive cells. The process of transport of glucose from intestinal lumen into the absorptive cell has two stages. In the first stage sodium ion from inside the cells are transported to interstitial fluid. This leads to low sodium concentration inside the cell.

How is glucose stored?

After your body has used the energy it needs, the leftover glucose is stored in little bundles called glycogen in the liver and muscles. Your body can store enough to fuel you for about a day.

Which tissue depends on insulin for glucose transport?

Skeletal muscle is the primary tissue responsible for insulin-dependent glucose uptake in vivo; therefore, glucose uptake by this tissue plays an important role in determining glycemia.

Where is glucose reabsorbed?

Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule.

How is glucose absorbed from intestine?

Glucose is absorbed through the intestine by a transepithelial transport system initiated at the apical membrane by the cotransporter SGLT-1; intracellular glucose is then assumed to diffuse across the basolateral membrane through GLUT2.

Is glucose stored in adipose tissue?

Triglyceride storage in adipose tissue comprises the principal energy reserve in mammals. Additionally glucose can be stored as glycogen in the fed state, primarily in liver and skeletal muscle, for mobilization during times of energy deficit. Adipose tissue also contains glycogen stores albeit at very low levels.

Where is glucose stored in the body?

Insulin helps glucose enter the body's cells to be used for energy. If all the glucose is not needed for energy, some of it is stored in fat cells and in the liver as glycogen. As sugar moves from the blood to the cells, the blood glucose level returns to a normal between-meal range.

How is glucose transported in the blood?

Glucose is transported across the cell membrane by specific saturable transport system, which includes two types of glucose transporters: 1) sodium dependent glucose transporters (SGLTs) which transport glucose against its concentration gradient and 2) sodium independent glucose transporters (GLUTs), which transport ...

What are glucose dependent tissues?

Glucose homeostasis is primarily dependent on the balance between glucose production by the liver and glucose consumption by insulin dependent tissues (such as muscle, adipose tissue) and noninsulin dependent tissues (such as brain).

Where are glut 3 receptors found?

GLUT3 is the most prominent glucose transporter isoform expressed in adult brain, where it tends to be preferentially located in neurones, rather than in other cell types, such as glia or endothelial cells. It is also widely distributed in other human tissues, having been detected in the liver, kidney and placenta.

Which tissue is most insulin-sensitive?

The insulin makes insulin-sensitive tissues in the body (primarily skeletal muscle cells, adipose tissue, and liver) absorb glucose which provides energy as well as lowers blood glucose.

In what part of the nephron would most glucose be reabsorbed?

Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule. This reabsorption is effected by two sodium-dependent glucose cotransporter (SGLT) proteins.

Is glucose reabsorbed by diffusion?

The glucose molecule then diffuses across the basal membrane by facilitated diffusion into the interstitial space and from there into peritubular capillaries. Most of the Ca⁺⁺, Na⁺, glucose, and amino acids must be reabsorbed by the nephron to maintain homeostatic plasma concentrations.

Why glucose is reabsorbed?

Renal glucose reabsorption is the part of kidney (renal) physiology that deals with the retrieval of filtered glucose, preventing it from disappearing from the body through the urine. If glucose is not reabsorbed by the kidney, it appears in the urine, in a condition known as glycosuria.
