Arrange the main steps that convert glucose into glycogen.
Answer
Glucose is phosphorylated to glucose-6-phosphate., Glucose-6-phosphate is converted to glucose-1-phosphate., Glucose-1-phosphate reacts with uridine triphosphate to form uridine diphosphate glucose., Glycogen synthase transfers glucose from uridine diphosphate glucose to a glycogen primer.
Explanation
### The order
1. Glucose is phosphorylated to glucose-6-phosphate as the first entry step.
2. Phosphoglucomutase shifts the phosphate to produce glucose-1-phosphate.
3. Glucose-1-phosphate is activated with uridine triphosphate to form uridine diphosphate glucose.
4. Glycogen synthase uses the activated glucose to extend the glycogen primer.
### Terms
- **Phosphoglucomutase**: An enzyme that shifts phosphate between carbon positions in glucose phosphate.
- **Primer**: A short existing glycogen chain that supports further synthesis.
### Remember
Activate glucose as uridine diphosphate glucose before adding it to glycogen.
