Question

Some glucose produced by gluconeogenesis is stored in the body as glycogen. Order the steps of glycogen synthesis. Not all descriptions accurately describe glycogen synthesis; therefore, not all the descriptions will be used.

Answer 1

The production of glycogen from glucose is termed as glycogenesis. It occurs in the cytosol and needs UTP and ATP, besides glucose. The following are the steps of glycogen synthesis:  

1. UDP-glucose pyrophosphorylase catalyzes the reaction of glucose-1-phosphatase and UTP to UDP - glucose, and PPi.  

2. Pyrophosphates transform PPi and water into two Pi.  

3. Glycogen synthase supplements a glucose unit from UDP-glucose to glycogen forming a bigger glycogen molecule and UDP.
