What is the main job of the electron carriers in cellular respiration?
A
Transport electrons and hydrogen atoms to the electron transport chain
B
Capture energy throughout the process of cellular respiration
C
Provide the reactants for the process of cellular respiration
D
Pump positive hydrogen ions and shuttle electrons across the electron transport chain and contribute to chemiosmosis
Explanation: 

Detailed explanation-1: -The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion, called the electron transport chain. As electrons move through the electron transport chain, they go from a higher to a lower energy level and are ultimately passed to oxygen (forming water).
