The liver helps regulate glucose levels in the blood by storing excess glucose as glycogen when levels are high and releasing glucose into the bloodstream when levels are low. It also helps convert other substances into glucose through a process called gluconeogenesis.
Glucagon signals the liver to break down stored glycogen into glucose and release it into the bloodstream to raise blood glucose levels. This helps to maintain a stable level of glucose in the blood when levels are low.
When blood glucose levels rise, the pancreas secretes insulin, which helps cells take up glucose from the blood, lowering blood glucose levels. When blood glucose levels are low, the pancreas secretes glucagon, which stimulates the liver to release stored glucose into the bloodstream, raising blood glucose levels back to normal.
The purpose of the glucose receptors is to detect blood glucose levels. The Islets of Langerhorn dispatch alpha cells to detect low blood glucose and beta cells to detect high blood glucose levels.
A) Blood glucose levels that fall too low signal the release of glucagon B) Blood glucose levels that rise too high signal the release of glycogen C) Blood glucose levels that rise too high signal the release of epinephrine D) Blood glucose levels that fall too low signal the release of insulin
A) Blood glucose levels that fall too low signal the release of glucagon B) Blood glucose levels that rise too high signal the release of glycogen C) Blood glucose levels that rise too high signal the release of epinephrine D) Blood glucose levels that fall too low signal the release of insulin
The other way around. When blood glucose levels are low, the liver converts stored sugar, glycogen, into blood sugar, glucose. You can remember it this way: glyco-GEN GEN-nerates glucose.
No
Well, a healthy level of blood glucose wouldn't be too high or too low. Instead, it would be in the middle between high and low. Unhealthy levels of blood glucose would be an extremely high number.
The body takes up more glucose
The pancreas is responsible for regulating blood glucose levels by producing insulin to remove glucose from the blood when levels are high, and producing glucagon to add glucose to the blood when levels are low.
high & low blood sugars, respectively
