Which best explains the relationship between glucose and insulin * Insulin enters the blood stream shortly after a meal, glucose is released by the pancreas to attach to glucose receptor sites, channels open into the cell allowing insulin to move in to start the process of cellular respiration when the body is deprived of energy rich glucose molecules, the liver releases insulin, the stored form of glucose to counter the low levels of glucose, thus returning the body back to homeostasis glucose enters the blood stream shortly after a meal, insulin is released by the pancreas to attach to insulin receptor sites, channels open into the cell allowing glucose to move in to start the process of cellular respiration After a workout, glucose levels in the bloodstream will drop, allowing insulin to return to the pancreas and cause the release of glucagon from the liver. This will return the body the homeostasis.
