Which two molecules generated by the krebs cycle pass their high-energy electrons to the electron transport chain?

Explanation:

Krebs cycle is a type of chemical reaction that occurs in a series manner and takes place in all aerobic respiration process. During this reaction acetyl- CoA enters in this cycle and reacts with oxaloacetate and forms citrate. Citrate converted into some other products and finally changes into oxaloacetate and thus the cycle continues. During the overall reaction carbon dioxide, , and ATP are generated.   and are responsible for the initiation of the electron transport chain by passing the electrons in the electron transport system. The electron moves in the electron transport system through different complex and finally goes to an oxygen molecule and forms a water molecule at the end of the electron transport chain.

the dissolution of polymer can be thermodynamically described in 2 steps.
