Arrange these glycolytic events in pathway order.
Answer
Glucose is phosphorylated to glucose-6-phosphate., Fructose-6-phosphate is phosphorylated to fructose-1,6-bisphosphate., Fructose-1,6-bisphosphate is split into triose phosphates., Phosphoenolpyruvate is converted to pyruvate.
Explanation
### The order
1. Glucose becomes glucose-6-phosphate, the first phosphorylated intermediate.
2. Isomerization and a second phosphorylation produce fructose-1,6-bisphosphate.
3. Aldolase splits this six-carbon compound into two three-carbon products.
4. After downstream reactions, phosphoenolpyruvate becomes pyruvate and generates adenosine triphosphate.
### Terms
- **Glucose-6-phosphate**: Glucose with a phosphate group on carbon six.
- **Phosphoenolpyruvate**: A high-energy glycolytic intermediate.
- **Aldolase**: The enzyme that cleaves fructose-1,6-bisphosphate.
### Remember
Glycolysis activates and splits glucose before harvesting energy from its three-carbon products.
