Question

Cyanide resistant pathway is

• A. Anaerobic respiration
• B. Aerobic respiration
• C. Both (A) and (B)
• D. None of these

Answer 1

The correct option is A Anaerobic respiration

Cyanide resistant respiration is a widespread phenomenon. It resides in the mitochondria and involves a cyanide-insensitive enzyme, the alternative oxidase. Cyanide-resistant respiration is typically used when the classical respiratory chain is impaired or absent (i.e., in anaerobically-grown cells shifted to normoxia or in respiratory-deficient cells).
