Glycolysis Glycolytic Pathway – Definition and Where Does Glycolysis Occur

Glycolysis Glycolytic Pathway

The glycolytic pathway is a sequence of biochemical reactions that produce energy in the form of adenosine triphosphate (ATP) from glucose. Glucose is a simple sugar that is obtained from the digestion of food.

• The glycolytic pathway begins with the conversion of glucose to glucose-6-phosphate by the enzyme glucose-6-phosphate dehydrogenase.
• Glucose-6-phosphate is then converted to fructose-6-phosphate by the enzyme fructose-6-phosphate aldolase.
• The fructose-6-phosphate is then converted to glyceraldehyde-3-phosphate by the enzyme glyceraldehyde-3-phosphate dehydrogenase.
• The glyceraldehyde-3-phosphate is then converted to 1,3-bisphosphoglycerate by the enzyme 3-phosphoglycerate kinase.
• The 1,3-bisphosphoglycerate is then converted to 3-phosphoglycerate by the enzyme phosphoglycerate mutase.
• The 3-phosphoglycerate is then converted to 2-phosphoglycerate by the enzyme phosphoglycerate dehydrogenase.
• The 2-phosphoglycerate is then converted to phosphoenolpyruvate by the enzyme enolase.
• The phosphoenolpyruvate is then converted to pyruv

Where Does Glycolysis Occur?

The answer to this question is that glycolysis occurs in the cytoplasm of the cell. This is a process that is responsible for the breakdown of glucose into pyruvate, and it occurs in a variety of different types of cells. The cytoplasm is the portion of the cell that is located outside of the nucleus, and it is responsible for a variety of different functions.

Glycolysis is the process that breaks down glucose into two molecules of pyruvate. This process occurs in the cytoplasm of the cell. The glycolysis reaction can be represented by the following equation:

C6H12O6 + 2ADP + 2Pi -> 2CH3COCO2 + 2ATP

The two molecules of pyruvate are then transported into the mitochondrial matrix, where the Krebs cycle and electron transport chain occur.
