Study Notes
Overview of Glycolysis
- Glycolysis is a metabolic pathway that converts glucose (C6H12O6) into pyruvate
- Occurs in the liquid part of cells, the cytosol
- Releases free energy used to form high-energy molecules ATP and NADH
Characteristics of Glycolysis
- Sequence of ten reactions catalyzed by enzymes
- Ancient metabolic pathway, widely occurring in other species
- Can occur in oxygen-free conditions, catalyzed by metal ions
Types of Glycolysis
- Embden–Meyerhof–Parnas (EMP) pathway: most common type, discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas
- Other pathways: Entner–Doudoroff pathway, heterofermentative and homofermentative pathways
