Which two molecules generated by the Krebs cycle pass their high-energy electrons to the electron transport
Sidana [21]

<u>Answer</u>:

The two molecules generated by the Krebs cycle that pass their high-energy electrons to the electron transport are NADH and  FADH2

<u>Explanation:</u>

During the process of the electron transport chain, one NADH gives rise to electrons and also the hydrogen ions, which has enough potential energy that can convert and produce 3 ATP molecules. Again in the electron transport chain the NADH and the FADH2 undergoes oxidation and releases energy in the form of the ATP. The process of generation of the ATP in the electron transport chain(ETC)  is also referred as the chemiosmotic phosphorolation.
