4.5: Glucose Regulation and Utilization in the Body
Your body’s ability to maintain equilibrium or a steady state in your blood glucose concentration is called homeostasis. It’s a critical part of normal physiology, because if your blood glucose gets too low (called hypo glycemia ), cellular function starts to fail, especially in the brain.
How insulin and glucagon regulate blood sugar - Medical News Today
2023年2月15日 · Insulin enables blood glucose to enter cells, where they use it to produce energy. Together, insulin and glucagon help maintain homeostasis, where conditions inside the body hold steady.
Glucose Regulation – Human Physiology - University of Guelph
Maintenance of Blood Glucose Homeostasis. Blood glucose concentrations are tightly maintained between 4 and 5 mmol/L (70mg/dL and 110mg/dL). If blood glucose concentration rises above this range, insulin is released, which stimulates body cells to remove glucose from the blood.
Blood sugar regulation - Wikipedia
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 …
Overview of Glucose Homeostasis | SpringerLink
2018年10月12日 · In overnight fasted individuals, plasma glucose concentration ranges between 3.6 and 5.5 mmol/L (65–99 mg/dL) and increases up to 8.9–10 mmol/L (160–180 mg/dL) in the fed state. At the whole-body level, the first step in glucose metabolism is …
Normal Glucose Homeostasis | SpringerLink
2017年7月21日 · This chapter discusses normal glucose physiology. It reviews the regulation of glucose production and utilization by complex mechanisms that are influenced by the nervous system, several hormones, and substrates all tightly linked so as to maintain optimal glucose...
The Endocrine Pancreas – Glucose Homeostasis
Blood glucose concentration is tightly maintained between 70 mg/dL and 110 mg/dL. If blood glucose concentration rises above this range, insulin is released, which stimulates body cells to remove glucose from the blood.
Cellular and systemic mechanisms for glucose sensing and homeostasis …
Pancreatic β-cells and α-cells are central to the maintenance of blood glucose homeostasis. Increased blood glucose level after meals stimulates pancreatic β-cells to secrete insulin, which promotes glucose uptake in cells and lowers glucose levels in the blood.
Frontiers | The Central Role of Glucokinase in Glucose Homeostasis…
2019年3月5日 · It is hypothesized that glucokinase (GCK) is the glucose sensor not only for regulation of insulin release by pancreatic β-cells, but also for the rest of the cells that contribute to glucose homeostasis in mammals.
Glucose Metabolism and Regulation: Beyond Insulin and …
2004年7月1日 · Glucose homeostasis: roles of insulin and glucagon. 1A. For nondiabetic individuals in the fasting state, plasma glucose is derived from glycogenolysis under the direction of glucagon (1). Basal levels of insulin control glucose disposal (2).
