The amount of oxygen liver cells require to react lactic acid to produce glucose or the glycogen?
The amount of oxygen liver cells require to react lactic acid to produce glucose or the glycogen is the oxygen debt. Threshold stimulus is the minimal amount of energy required to contract a muscle fiber.
What are glucose concentrations in the blood largely controlled by?
Liver
What organ is responsible for blood glucose?
The chloroplast
Why does your body need glycogen?
The body's blood glucose level needs to remain in homeostasis (about 90mg/100mL). if the blood glucose level rises, the beta cells of the pancreas will secrete insulin into the blood. the body cells will take up more glucose and the liver also takes up glucose and stores it as glycogen. these mechanisms cause the blood glucose level to drop back to set point and the stimulus for insulin release stops. Alternativey if the blood glucose level drops the alpha cells of th pancreas will release the hormone glucagon into the blood. this causes the liver to break down glycogen and therefor release glucose into the blood.blood glucose level will then rise back to set point and the stimulus for glucagon release stops. Therefore glyogen forms as an energy reserve that can be quickly mobilized to meet a sudden need for glucose. So when glucose is needed by the body, glycogen will be broken down and converted back to glucose to be used by the body. Therefore glycogen forms an important part of the process for the maintenance of glucose homeostasis in the body.
How does the feedback control system for insulin production work?
The control of blood glucose levels operates by what is known as a negative feedback mechanism. Here is a summary of the 2 control loops.When the blood glucose level goes upBlood sugar (glucose) rises;The pancreas detects the rise;The pancreas pumps out insulin into the blood;Insulin helps the uptake of glucose into muscles and other cells;This causes the blood glucose level to fall to its normal set point; andThe pancreas detects the fall and switches off insulin production.When the blood glucose level goes downBlood sugar (glucose) drops;The pancreas detects the drop in blood sugar;The pancreas switches on the output of glucagon into the blood;Glucagon signals the liver to break down glycogen into glucose;The liver releases glucose into the bloodstream;Blood glucose goes up to its normal set point; andThe pancreas detects the rise in blood sugar and switches off glucagon release.
The liver reacts to a high level of glucose in the blood glucose in the blood by converting some of the glucose to?
Glucose in the blood is converted to glycogen due to the actions of insulin. Glycogen is insoluble, so it doesn't affect the osmotic balance in the cytoplasm of our muscle and liver cells.Glycogen is stored in the liver and it is released into the blood stream if the flood glucose level drops, if at fasting or after many hours of food intake.
When the glucose level in the blood is too low this hormone prompts the release of glucose stored in the?
Liver
What organ in the body detects changes in blood glucose level?
the liver
Difficulties maintaining blood glucose level bile production and the production of blood proteins?
The liver!
How does the blood control the blood sugar?
When the blood sugar is very high in the body, the pancreas makes a hormone called 'insulin' this hormone tells the liver to take the excess glucose out of the blood. The glucose is stored as glycogen, a type of sugar, in the liver. The glucose in the blood falls to its correct level. Also when we excercise, the muscles in our body use up a lot of glucose. If blood glucose falls, the pancrease makes another hormone 'glucagon'. This tells the liver to convert some glycogen into glucose and put it back into the blood. Glucose in the blood rises to its correct level.
What is Glycagon?
Glycagon is a 29 amino acid polypeptide and is an extremely potent hyperglycemic agent. It's a hormone that is produced from alpha cells in the pancreas. Its target is the liver, where it promotes the: 1) break down of glycogen to glucose 2) synthesis of glucose from lactic acid and from noncarbohydrate molecules 3) release of glucose into the blood by liver cells, raising blood glucose levels
How does the liver help to regulate glucose levels in the blood?
When the blood sugar is very high in the body, the pancreas makes a hormone called 'insulin' this hormone tells the liver to take the excess glucose out of the blood. The glucose is stored as glycogen, a type of sugar, in the liver. The glucose in the blood falls to its correct level. Also when we excercise, the muscles in our body use up a lot of glucose. If blood glucose falls, the pancrease makes another hormone 'glucagon'. This tells the liver to convert some glycogen into glucose and put it back into the blood. Glucose in the blood rises to its correct level.
What organ stores excess blood sugar as glycogen?
The liver and skeletal muscle store glucose as glycogen. The liver can make glucose from proteins and release it from glycogen to help keep blood glucose at a normal level when we are fasting.
What signals the liver to store or release glucose?
Glucagon is a hormone created by the pancreas that signals the liver to release glucose when the blood sugar level is dangerously low by converting glycogen (glucose converted for long term "storage") into glucose in the process known as glycogenolysis. Insulin is the hormone created by the pancreas that tells the liver to convert excess glucose into glycogen when the blood sugar level is high in the process known as glycogenesis.
The organ most responsible for extracting and converting lactic acid to pyruvic acid and which ultimately reforms and releases free glucose via the Cori cycle into the blood is the?
liver
What hormone causes liver cells to release glucose?
The hormone glucagon stimulates the liver to release glucose into the blood when glucose levels are low.
The liver converts lactic acid to X which it then can convert to X for storage can you please tell me what are the two words that replace X mark?
The liver converts lactic acid to glucose, which it then can convert to glycogen for storage.
