Study Notes
Glycolysis Reactions
- Hexokinase is the enzyme that catalyzes the conversion of glucose to glucose-6-phosphate in the first stage of glycolysis.
Rate-Limiting Step
- The product of the third reaction in glycolysis, which is also the rate-limiting step, is fructose-1,6-bisphosphate.
High-Energy Intermediate
- The reaction involving the formation of the first high-energy intermediate in glycolysis is the conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate.
Final Product of Glycolysis
- The final product of glycolysis under aerobic conditions is pyruvate.
Energy Metabolism in Red Blood Cells
- Due to the absence of mitochondria, red blood cells rely solely on glycolysis for energy production.
