Multiple choice

Cabon monoxide inhibits mitochondrial electron transport by

  1. inhibiting the electron transfer of complex I

  2. blocking electron transport at the level of the cytochrome b-cytochrome c, complex

  3. binding to the oxygen-binding site of cytochrome oxidase

  4. binding to haemoglobin in the erythrocytes and therefore, blocking the transport of oxygen to tissues
