Homework Answers
Answer:
Drugs mentioned in question are categorised as follows:
- Electron transport inhibitors
- Rotenone
- Antimycin
- Cyanide
- Malonate (succinate dehydrogenase inhibitor)
- Uncoupling agents
- 2,4-Dinitrophenol (DNP)
- Carbonyl cyanide p-[trifluoromethoxy]-phenyl-hydrazone (FCCP)
- Oligomycin (inhibitor of oxidative phosphorylation)
These are not inhibitors of the glycolysis
