What compound receives electrons from NADH?

a. FMN

b. ubiquinone

c. cytochrome${\mathrm{C}}_1$

d. oxygen

The transport (ETC) could be a set of pharmacological activities that comprises the rapid transfer of energy from one constituent after another until they approach oxygen, the tip electrostatic bond. These electrons cause molecular oxygen to still be diminished, ends up in in the liquid. ETC consists of the subsequent facilities: complex I, II, III, and IV.

Formula $Q$ is a chemical that act as a bridge across complexes I and II. That's nothing over an electron donor. Complex I delivers electron to the present now.

The electrons pass to cytochrome $C1$by Fe-S.

While oxygen seems to be the tip electron donor, it shouldn't collect electron (reduced nicotinamide adenine).

The Inositol (cofactor $1$primary) portion of Group I (NADH reductase) takes electron and delivers them onto new addition (Q). As a response, NADH transfers atoms for FMN.
