Q807

In Cyanide resistant respiratory pathway, electron is transported through

A.
Pentose phosphate pathway
B.
Hexose mono phosphate Shunt
C.
Rotenone insensitive NADH dehydrogenases
D.
AoX or Alternate Oxidase
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
In Cyanide resistant respiratory pathway, the electron is transported through AoX or Alternate Oxidase. The flow of electrons from reduced coenzymes to ubiquinone is the same as in the usual mitochondrial electron transport chain.
Cyanide Resistant Respiration (CRR) is a widespread metabolic pathway among yeasts, that involves a mitochondrial alternative oxidase sensitive to Salicyl Hydroxamic Acid (SHAM).
