NADH 2 enters the ETC in Step #1 . FADH 2 does not enter the ETC until Step #3 .

NADH 2 enters the ETC in Step #1 . FADH 2 does not enter the ETC until Step #3. Steps #1 thru #3: two H + ions and two electrons are passed from NADH (oxidized back to NAD+) to FMN reducing it to FMNH 2 . This passes 2H + ions and 2e - on to CoQ which is reduced to CoQH 2 .
