Glycolysis is a metabolic pathway

It converts glucose into pyruvate

Occurs in the cytoplasm of cells

Glucose is broken down into two molecules of glyceraldehyde-3-phosphate

Requires two ATP molecules for activation

Catalyzed by various enzymes

Glyceraldehyde-3-phosphate is further broken down into pyruvate

ATP and NADH are produced

Substrates are oxidized and reduced during this phase

Allosteric regulation by various molecules

Hormonal regulation by insulin and glucagon

Pyruvate can be further metabolized in different ways

Depends on oxygen availability and cell type

In the absence of oxygen, pyruvate can be converted into lactate through fermentation

In the presence of oxygen, pyruvate enters the citric acid cycle
