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.

What is the main job of the electron carriers in cellular respiration? 

• Transport electrons and hydrogen atoms to the electron transport chain 
• Capture energy throughout the process of cellular respiration
• Provide the reactants for the process of cellular respiration
• Pump positive hydrogen ions and shuttle electrons across the electron transport chain and contribute to chemiosmosis
