Question

What is the difference between glycolysis and gluconeogenesis?

Answer 1

Hint: All the nutrients we eat is converted into ATP which is the form of utilisable energy. Glucose is the immediate source of energy. The oxidation of glucose produces energy. Glycolysis is the breakdown of glucose and gluconeogenesis is the formation of glucose.

Complete answer:
Respiration is the important process in which glucose is broken down by the oxidation process releasing carbon dioxide, water and energy in the form of ATP. This process consist of two steps glycolysis and kerb cycle. The glycolysis is the catabolic process where the glucose is broken down into pyruvate.
By the process of gluconeogenesis, the pyruvate from the other nutrient sources non-carbohydrate is converted into glucose.

Let us discuss the difference between the two.

Glycolysis	Gluconeogenesis
Glycolysis is the process of conversion of glucose into pyruvate.	It is the process by which glucose is produced from non-carbohydrate sources like proteins, fats.
It is a catabolic process.	It is an anabolic process.
It is an exergonic process.	It is an endergonic process.
It occurs in the cytosol.	It occurs both in mitochondria and cytosol.
The raw material for the reaction is glucose.	The raw material for this process is amino acid, lipids, fatty acid, glycerol.
This process takes place when the cell energy is low.	This process takes place when the cell energy is high.
It is a 10-step reversible reaction.	It is a 11-step reaction which involves 2 irreversible reactions.

Note: The glucose in our body is stored in the form of glycogen in the liver and muscles. The process by which the glucose is converted into glycogen is known as glycogenesis. It takes place when the blood glucose level is high.
