Q1. A patient is rushed to the ER with suspected cyanide poisoning, which inhibits mitochondrial enzymes. Which specific stage of respiration is directly blocked?
Answer: Electron transport chain
Explanation: Cyanide binds to cytochrome oxidase, halting the electron transport chain. Glycolysis is wrong because it occurs in the cytosol independently.
