The main reason why [AMP] is a key regulator of many metabolic reactions (rather than [ATP]) is: Group of answer choices
1. DeltaG of ATP -> AMP hydrolysis is higher than DeltaG of ATP ->
2. ADP hydrolysis [ATP] is typically greater than [AMP]
3. ATP is the form present in nucleic acids
4. The relative change in [AMP] is usually much greater than the relative change in [ATP]
5. AMP is less charged than ATP
