Which of the following ranks the redox-active species of the electron transport chain in order of decreasing electron affinity?

a. O2 > FAD > CoQ > NAD+
b. NAD+ > FAD > CoQ > O2
c. O2 > CoQ > NAD+ > FAD
d. O2 > CoQ > FAD > NAD+

Respuesta :

Answer:

d. O2 > CoQ > FAD > NAD+

Explanation:

O2 > CoQ > FAD > NAD+

Because the reason is O2 is the last electron acceptor in the chain for a reason. FAD is also introduced later in the ETC(Electron transfer chain) than NAD+ and generates less ATP.
