What hormone is involved in blood glucose regulation?
There are two hormones that regulate blood glucose levels. One is insulin. This horemone "carries" glucose into the cell. No glucose and the cell starves and the glucose levels get higher in the blood. The second hormone takes glucose out of liver storage and increases the glucose in the blood. These two are a feedback mechanism that keeps the levels in a normal range.
Which part of the endocrine system is responsible for controlling blood sugar levels and glucose metabolism throughout the body?
pancreatic islets
Describe how hexokinase works?
It can work maximally at low glucose concentrations (fasting levels of glucose are 3-5mM) so that it is always working at vmax
How does glucose metabolism demonstrate a homeostasis metabolism?
the homeostatic mechanism governs glucose metabolism and the glucose metabolism demonstrates the homeostatic mechanism in its regulation of the glucose fuel supply to the central nevrous system. (Spelled nevrous wrong)
Glucose can be elevated in the blood of a diabetic person Relate this information to glucose in the urine and glucose carriers?
When blood glucose levels are high in a diabetic person, the kidneys may not be able to reabsorb all the glucose, leading to glucose spilling into the urine (glucosuria). Glucose carriers, such as SGLT2 in the kidney tubules, may become saturated, causing excess glucose to be excreted in the urine. This can be an indication of uncontrolled diabetes and a mechanism for reducing high blood glucose levels.
Why is insulin associated with the maintenance of blood glucose levels?
The pancreas releases insulin to lower the level of glucose in blood, and on the other hand, for the balance, it also secretes glucagon to elevate the level of glucose. Insulin is one half of the balance mechanism for glucose levels. Too much and too little glucose has damaging effects on the body and it's cells.
What hormone reduces blood glucose levels and what hormone raises blood glucose levels?
Glucagon is the hormone that raises blood glucose levels.
What is the feedback mechanism of insulin?
An increase in blood sugar levels cause the release of the hormone insulin by the pancreas. Insulin then lowers this blood sugar level restoring it to original non-lethal blood glucose levels.
How does hexokinase maintain homeostasis?
Hexokinase helps maintain homeostasis by catalyzing the first step of glucose metabolism, converting glucose to glucose-6-phosphate, which traps glucose inside cells. This helps regulate blood glucose levels by controlling glucose uptake and utilization in cells. By initiating glycolysis, hexokinase also produces ATP, which is essential for energy production and cellular function.
Does glycogenolysis increase blood glucose levels?
Yes, glycogenolysis is the breakdown of glycogen into glucose, which can increase blood glucose levels.
