Ball-and-stick model of a glucose molecule. Blood sugar regulation is the process by which the levels of blood sugar, the common name for glucose dissolved in blood plasma, are maintained by the body within a narrow range. The regulation of glucose levels through Homeostasis. This tight regulation is referred to as glucose homeostasis.
Glucose homeostasis, when operating normally, restores the blood sugar level to a narrow range of about 4.4 to 6.1 mmol/L (79 to 110 mg/dL) (as measured by a fasting blood glucose test). [ 10 ] The global mean fasting plasma blood glucose level in humans is about 5.5 mmol/L (100 mg/dL); [ 11 ] [ 12 ] however, this level fluctuates throughout ...
Figure 2: Regulation of metabolic pathways maintains blood glucose concentration at approximately 5 mM in humans. Blood glucose levels are maintained at a steady state concentration by balancing the rate of entry of glucose into the blood stream (i.e. by ingestion or released from cells) and the rate of glucose uptake by body tissues. [1]
Homeostasis regulates, among others, the pH, sodium, potassium, and calcium concentrations in the ECF. The volume of body fluid, blood glucose, oxygen, and carbon dioxide levels are also tightly homeostatically maintained. The volume of extracellular fluid in a young adult male of 70 kg (154 lbs) is 20% of body weight – about fourteen liters.
The glucose cycle can occur in liver cells due to a liver specific enzyme glucose-6-phosphatase, which catalyse the dephosphorylation of glucose 6-phosphate back to glucose. Glucose-6-phosphate is the product of glycogenolysis or gluconeogenesis , where the goal is to increase free glucose in the blood due body being in catabolic state.
GLUT4 has a Km value for glucose of about 5 mM, which as stated above is the normal blood glucose level in healthy individuals. GLUT4 is the most abundant glucose transporter in skeletal muscle and is thus considered to be rate limiting for glucose uptake and metabolism in resting muscles. [ 8 ]
A rise in the blood glucose concentration causes them to release insulin into the blood, which has an effect particularly on the liver, but also on fat and muscle cells, causing these tissues to remove glucose from the blood. When the blood sugar falls the pancreatic beta cells cease insulin production, but, instead, stimulate the neighboring ...
IR is insulin resistance and %β is the β-cell function (more precisely, an index for glucose tolerance, i.e. a measure for the ability to counteract the glucose load). Insulin is given in μU/mL. [7] Glucose and insulin are both during fasting. [2] This model correlated well with estimates using the euglycemic clamp method (r = 0.88). [2]
