Most of the glucose secreted by the liver during fasting is due to
A)glycogenolysis.
B)gluconeogenesis.
C)lipolysis.
D)deamination.

Question

Quizplus · Accepted Answer

Gluconeogenesis is the process by which glucose is synthesized from non-carbohydrate sources, such as amino acids and fatty acids, and is the main mechanism responsible for glucose secretion by the liver during fasting. Glycogenolysis (A) is the breakdown of glycogen into glucose and occurs mainly during periods of physical activity. Lipolysis (C) is the breakdown of fats into fatty acids and glycerol and is not a primary source of glucose during fasting. Deamination (D) is the removal of an amino group from an amino acid and does not directly contribute to glucose production.
