what is G6P's relationship with glycogen synthase?
G6P is an allosteric activatoer
- means high ATP, so have energy to do biosynthesis
___ transfers phosphate from ATP to glycogen synthase, stabilizing T-state and inactivating glycogen biosynthesis
phosphorylation cascades
what happpens when glycogen biosynthesis is on?
1. glycogn synthase is ON, so it is in R-state
- ATP/G6P/glucose is high
2. glyccogen phosphorylase is OFF, so is in T-state
- AMP low
what happens when the body has excess sugar and energy?
means that ATP/G6P/glucose is high & AMP low
- so glycogen synthase ON (R-state)
what happens when the body has low sugar & high energy demand?
means low G6P/ATP/glucose and high AMP
- so glycogen phosphorylase (breakdown) ON (R-state)
