Question

Study the incorrect statement with respect to an overview of the electron transport system $(ETS)$.

• A. Ubiquinone receives reducing equivalents via., $FADH_2$ (complex II) that is generated during oxidation of succinate in the $TCA$ cycle
• B. As the electrons move down the system, energy is released and used to form $ATP$
• C. $2ATPs$ are formed for every pair of electrons that enters by way of $NADH$ and $3ATPs$ are formed for every pair of electrons that enters by way of $FADH_2$
• D. Oxygen, the final $e^-$ acceptor becomes a part of water

Answer 1

Answer: (C)

$2ATPs$ are formed for every pair of electrons that enters by way of $NADH$ and $3ATPs$ are formed for every pair of electrons that enters by way of $FADH_2$

Answer 2

$3\,ATPs$ are formed for every pair of electrons that enters by way of $NADH$ and $2\, ATPs$ are formed for every pair of electrons that enters by way of $FADH_2$.
