s 2017 Assignment 6 60 pts Due become more and BICH 411 Spring the before the below, (11 pts) When electron is blocked, For each ofthe conditions as, CuA, & CuB those beyond the block become more bit, c c, a and the state of oxidation of FMN, FAD, CoQ, cytochromes bu, (A) abundant NADH and O2, but cyanide added. Cytochrome as (B) abundant NADH, but O2 exhausted. (C) abundant succinate, but O2 exhausted (D) abundant O2, but NADH exhausted (E) abundant NADH and O. Rotenone added (F) abundant succinate and Oh Rotenone (G abundant succinate and O2 Carboxin added. (H) abundant NADH and on Carboxin added. abundant NADH, succinate and O2, antimycin A added

Explanation / Answer

A. Due to addition of cyanide ,cytochrome oxidase gets inhibited,which results in all the carriers becoming reduced.

B. Due to exhaustion of Oxygen,there is no terminal electron acceptor present,which results in all carriers becoming reduced.

D .In the absence of NADH, and oxygen abundance results in all the carriers becoming oxidised,no carrier will be reduced.
