Glycolysis

Various steps of Glycolysis :

Introduction: 

➡️The term glycolysis is derived from the Greek word glykys and sugar (Glykys means sweet and lysis means splitting). The complete pathways of glycolysis was discovered by the three scientists namely Embden,Meyerhoff, And Parnas in the year of 1940.

➡️Glycolysis is the process by which a molecule of glucose is degraded to form two molecule of three carbon containing compound, pyruvate .

This happens by a series of enzyme catalyzed reactions.

➡️Glycolysis is regarded as  an almost universal central pathway of Glucose catabolism.

In some mammalian tissue cell types ( such as Red blood cell, brain ,sperm etc) glycolysis is the sole source of metabolic energy due to the breakdown of the 6 carbon containing molecule glucose, which provides energy.

➡️There is also present , many anaerobic microorganisms which are also completely dependent on the process of glycolysis,to acquire energy.

➡️Some aquatic plants are dependent on the process of glycolysis , for energy.

➡️ The enzymes which takes part in the process of glycolysis are present in the cytosomal fraction of the cell.

➡️If the process of glycolysis happens in the absence of oxygen then it is known as anaerobic condition,and in this condition lactate is the final product.

➡️And If the process of glycolysis happens in the presence of oxygen then it is known as aerobic condition, and in this condition pyruvate is the final product, which then further oxidized to produce carbon dioxide and water.
