If the delta G of a reaction is negative, which response shows the best conclusion for that reaction? 

• The reaction will release more energy than was needed to form the reaction.
• Energy from the reaction can be used to do work. 
• Energy is absorbed by the reaction which then can be used to power other reactions. 
• Energy is absorbed within the reaction and distributed unevenly throughout the molecule.

Why is ATP considered the most significant energy carrying molecule? 

• It's delta G is negative. 
• ATP has different bond energy between its phosphate groups. 
• ATP can hold large amounts of energy between all of its bonds. 
• ATP's positive delta G contributes to the large amounts of energy between its 3rd and 2nd phosphate groups.
