THE UPTAKE OF GLUCOSE INTO CELLS AND THE ROLE OF INSULIN IN GLUCOSE TRANSPORT
Canadian Journal of Biochemistry, 1964This presentation has been restricted to the role of insulin in glucose transport in muscle cells and deals mainly with experiments using the perfused rat heart. The several possible means for glucose transfer into cells, diffusion, pores, pinocytosis, carriers, and dimerization, have been discussed; and arguments in favor of the carrier theory, namely,

Effect of insulin on the glucose uptake of protozoa
Experientia, 1975Insulin stimulates the glucose uptake of Tetrahymena pyriformis. This shows the presence of insulin receptors in Tetrahymena, consequently receptors may be present in a level of phylogenesis, where the natural contact between the given hormone and the cell is unnecessary and impossible.

Cellular Regulation of Glucose Uptake by Glucose Transporter GLUT4
2014GLUT4 is regulated by its intracellular localization. In the absence of insulin, GLUT4 is efficiently retained intracellularly within storage compartments in muscle and fat cells. Upon insulin stimulation (and contraction in muscle), GLUT4 translocates from these compartments to the cell surface where it transports glucose from the extracellular milieu

Study of Glucose Uptake in Adipose Cells
2008Glucose is the main metabolic fuel in mammalian cells. Glucose entry into cells is facilitated by a family of ubiquitously expressed glucose transporter proteins. Typically, glucose transporters are localized on the plasma membrane. One notable exception is the glucose transporter isoform 4 (Glut4), which is specifically expressed in insulin sensitive ...

Regulation of Glucose Uptake by Muscle
1962Publisher Summary It is now recognized that a number of factors can influence the uptake of glucose by muscle. Some are of physiological importance and these include hormones, notably insulin, growth hormone, corticosteroids, and adrenaline and possibly thyroxine and glucagon, and nonhormonal factors such as the availability of oxygen, the ...

Uptake of glucose by bacteria in the sediment
Marine Biology, 1978A method is described for the incubation of undisturbed sediment cores under in situ conditions with the addition of low concentrations of 14C-glucose. Data are presented for respiration, gross uptake and actual uptake rate of glucose by bacteria in sandy, wave-washed beaches of the Baltic Sea.

The uptake of Glucose and gluconate by Pseudomonas putida
Molecular and Cellular Biochemistry, 1975The uptake of glucose and gluconate is under inductive control in Pseudomonas putida. Glucose, gluconate, and 2-ketogluconate were each good nutritional inducers of these transport abilities. Glucose and gluconate uptake obeyed saturation kinetics: the apparent Km for glucose was 6 mM and that for gluconate was 0.5 mM.

Measurement of Glucose Uptake in Cultured Cells
Current Protocols in Pharmacology, 2015AbstractFacilitative glucose uptake transport systems are ubiquitous in animal cells and are responsible for transporting glucose across cell surface membranes. Evaluation of glucose uptake is crucial in the study of numerous diseases and metabolic disorders such as myocardial ischemia, diabetes mellitus, and cancer.

Uptake of glucose and orthophosphate by the American oyster
Life Sciences, 1975Abstract The uptake, by oysters, of glucose is approximately 10–15 ng/hr/g wet weight, when glucose concentration in the saline was at 50 μg/ml. The removal of inorganic orthophosphate was approximately at a rate of 0.36 ng/hr/g wet weight. Radioactive studies indicate that these substrates are metabolized by oysters.
