Galactose-1-phosphate uridyltransferase transfers a uridyl group from uridine diphosphate glucose (UDP-glucose) to galactose-1-phosphate, producing uridine diphosphate galactose and glucose-1-phosphate.
Answer
true
Explanation
### Why this is right
This is the central transfer reaction in the described galactose pathway. Galactose-1-phosphate reacts with UDP-glucose to yield UDP-galactose and glucose-1-phosphate.
### The concept
UDP-galactose can be converted into UDP-glucose and contributes to lactose synthesis. Glucose-1-phosphate can enter glycogen metabolism or be converted toward glycolysis.
### Terms
- **UDP-glucose**: Activated glucose linked to uridine diphosphate.
- **UDP-galactose**: Activated galactose used in carbohydrate synthesis.
- **Galactose-1-phosphate uridyltransferase**: The enzyme that transfers the uridyl group in this reaction.
### Remember
The transferase reaction links galactose metabolism to glucose and glycogen pathways.
