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
