• Absorption of substances takes place in different parts of the alimentary canal, like the mouth, stomach, small intestine, and large intestine. 
• However, maximum absorption occurs in the small intestine.
• The small intestine is the principal organ for the absorption of nutrients.

The correct answer is Glycogen 

Key Points

• Glycogenolysis is a biochemical process in which glycogen breaks down into glucose-1-phosphate and glucose.
• The site of this reaction is hepatocytes and myocytes cells.
• Glycogenolysis occurs primarily in the liver and then it is  stimulated by the hormones glucagon and epinephrine (adrenaline)
• During starvation there is a decrease in the blood glucose level, there is an increase in the level of glucagon and is secreted by the pancreas.
• Simultaneously there is decreased level of insulin secretion because of the actions of insulin, which are aimed at increasing the storage of glucose in the form of glycogen in cells and this process opposes the actions of glucagon.
• During this process, glucagon travels to the liver, where it stimulates glycogenolysis.
• Enzymes involved in the regulation of the process are
  • Phosphorylase kinase catalyzes the interconversion between glucose-1-phosphate (G-l-P) and glucose-6-phosphate (G-6-P)
  • Glycogen phosphorylase
