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.
Most of the lactic acid remaining after exercise is converted back into glucose by the liver through a process called gluconeogenesis. This glucose can then be used as energy by the body or stored as glycogen in the muscles and liver for future use.
This process is known as glycogenolysis, where stored glycogen in the liver is broken down into glucose and released into the blood to maintain blood glucose levels.
Liver
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.
liver. The liver is responsible for extracting lactic acid from the blood and converting it back to pyruvate through the Cori cycle. This process allows the liver to produce glucose to be released into the blood for energy.
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.

The liver!
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.
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 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.
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.
