Botany - Respiration in Plants Question with Solution | TestHub

In electron transport chain electrons transport through a series of carriers.  H⁺of NADH⁺  (received from krebs cycle) is accepted by FAD as a result of which FAD is reduced to FADH⁺and NADH⁺is oxidised to NAD. Reduced FADH⁺is oxidised by CoQ, with the formation of CoQH⁺ . H⁺ions then move to Cyt b, then Cyt c, Cyt a and Cyt${\text{aa}}_3$. Ultimately these H⁺are accepted by O₂and H₂O is formed.
