Study Notes

Glycolysis Overview

Glycolysis is a metabolic pathway that converts glucose (C6H12O6) into pyruvate.
It occurs in the cytosol, the liquid part of cells, in most organisms.

Energy Production

The free energy released in glycolysis is used to form high-energy molecules:
- Adenosine triphosphate (ATP)
- Reduced nicotinamide adenine dinucleotide (NADH)

Enzymatic Reactions

Glycolysis is a sequence of 10 reactions catalyzed by enzymes.

Evolutionary Significance

The widespread occurrence of glycolysis in other species suggests it is an ancient metabolic pathway.
Glycolysis can occur in oxygen-free conditions, similar to the Archean oceans, and can be catalyzed by metal ions rather than enzymes.

Types of Glycolysis

The most common type of glycolysis is the Embden–Meyerhof–Parnas (EMP) pathway, discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas.
Other types of glycolysis include:
- Entner–Doudoroff pathway
- Heterofermentative pathways
- Homofermentative pathways
