Answer :
The approximate percent of O₂ saturation of hemoglobin in blood vessels returning from liver cells when the concentration of glucagon in the blood is high versus low is 10% when glucagon is high and 75% when low.
What are the Oxygen and Glucagon levels in the blood?
High glucagon levels causes blood pH to become slightly acidic, and the acidic pH curve (due to high glucagon) enters at 10% of O₂ hemoglobin saturation will be found in blood vessels. Whereas at low glucagon levels i.e. pH 7.4 is incorporated at 75% of O₂ hemoglobin saturation present in blood.
Glucagon breaks down glycogen in the liver to glucose and enables blood glucose to reach cells.
