Question

Excess glucose gets stored in liver in the form of:
1. Glycogenesis
2. Glycolysis
3. Glucagon
4. Glycogen

Answer 1

Correct Answer - Option 4 : Glycogen

Excess glucose gets stored in the liver in the form of Glycogen.

• Glucose is produced by breaking down carbohydrates in the small intestine.
• Glucose then enters the bloodstream
• During fasting, the glucose level will be 4.5-5.5 mmol/L while after eating it rises above 7 mmol/L and then falls back to normal within 2 hours of eating.
• Excess glucose is stored in the liver and muscles in the form of Glycogen as it is insoluble and cannot be broken down readily.  
• Glycogen formation is activated by Insulin.

 

•  Glycogenesis: The process of synthesis of Glycogen is called Glycogenesis. This happens when there are excess levels of glucose in the blood. 
•  Glycolysis: It is a series of reactions that convert Glucose(six-carbon molecule) into Pyruvate(three-carbon molecule), 2 ATP and 2 NADH molecules. 
•  Glucagon: It is a peptide hormone that helps in regulating blood glucose levels. It counter-reacts to the actions of insulin. Thus, Glucagon stimulates glucose production and increases blood glucose levels.
