Discuss how the adenylate energy charge regulates metabolism and why it is a useful parameter to monitor

Discuss how the adenylate energy charge regulates metabolism and why it is a useful parameter to monitor. Explain how it affects enzymes and pathways from glycolysis all the way through to oxidative phosphorylation when levels of any of the adenylates change (give specific examples). Also, discuss why plants are generally less affected by a change in the adenylate energy charge compared to animals?
