What is the key enzyme involved in glycogenesis?
What is the key enzyme involved in glycogenesis?
- Glycogen synthase (correct)
- Branching enzyme

How is glycogen synthesis initiated?
How is glycogen synthesis initiated?
- Through the addition of glucose units to reducing ends
- Through the formation of a 1-6 glycosidic bond
