Study Notes
Glycolysis Overview
- The main purpose of glycolysis is to convert glucose into pyruvate, generating energy for the cell.
Location and Types of Glycolysis
- Glycolysis usually occurs in the cytosol of cells in most organisms.
- The most common type of glycolysis is the Embden–Meyerhof–Parnas pathway.
Significance in Abiogenesis
- Glycolysis is significant in the context of abiogenesis, as it may have played a role in the origin of life on Earth.
ATP Yield in Simple Fermentations
- The net yield of ATP molecules from the metabolism of one molecule of glucose to two molecules of pyruvate in simple fermentations is 2.
Discovery of the Embden–Meyerhof–Parnas Pathway
- The Embden–Meyerhof–Parnas pathway was discovered by Gustav Embden, Otto Meyerhof, and Jakub Karol Parnas.
Early Experiments on Glycolysis
- French scientist Louis Pasteur conducted experiments in the 1850s, which began the elucidation of the glycolysis pathway.
Comparison of ATP Yield in Aerobic and Anaerobic Respiration
- Eukaryotic aerobic respiration produces 36-38 additional molecules of ATP for each glucose molecule, compared to anaerobic respiration.
Function of Inorganic Compounds in Anaerobic Respiration
- Inorganic compounds, such as nitrate, sulfate, and carbonate, serve as electron acceptors in many bacteria's use of anaerobic respiration.
Elucidation of the Glycolysis Pathway
- It took approximately 70 years to fully elucidate the pathway of glycolysis.
