Question

What is the total number of ATP produced in Glycolysis?

Answer 1

We know that glycolysis is derived from the Greek words [glucose- sweet or sugar; lysis- dissolution]. It is a universal pathway in the living cells. Glycolysis is defined as the sequence of reactions converting glucose/glycogen to pyruvate or lactate, with the production of ATP.

Complete answer:
As we know that the cellular respiration that takes place in the cytosol of the cell. The energy produced is in turn involved in the production of ATP [Adenosine Triphosphate]. ATP is known as the energy currency of the cell because it provides energy to the cell for its working. Also, Glycolysis cycle is often referred to as Embden-Meyerhof-Parnas pathway which is EMP pathway in honour of the biochemists who made a major contribution to the knowledge of glycolysis. Glycolysis is a crucial pathway for ATP synthesis in tissues lacking mitochondria, e.g. erythrocytes, cornea, lens etc. Glycolysis is very essential for the brain which is dependent on glucose for energy. Thus, the intermediates of glycolysis are functional for the synthesis of amino acids and fat.
The total number of ATP produced in glycolysis is four from one glucose molecule. Two molecules of ATP are utilized in the first half of glycolysis so there is a net gain of four ATP molecules in glycolysis. Also, four NADH molecules are also produced in glycolysis.

Note:
Remember that glycolysis is a series of ten reactions that are catalyzed by enzymes. It is possible to transform most monosaccharides, such as fructose and galactose, to one of these intermediates. Rather than simply being used as steps in the overall reaction, the intermediates can also be directly useful.
