    The order of occurrence of the cytochromes in the \[{{F}_{1}}\] particles is [MHCET 2002]

    A) \[cyt\text{ }b,\text{ }cyt\text{ }c,\text{ }cyt\text{ }a-cyt\text{ }{{a}_{3}}\]

    B) \[cyt\text{ }c,\text{ }cyt\text{ }b,\text{ }cyt\text{ }a-cyt\text{ }{{a}_{3}}\]

    C) \[cyt\text{ }a,\text{ }cyt\text{ }b,\text{ }cyt\text{ }c-cyt\text{ }{{a}_{3}}\]

    D) \[cyt\text{ }{{a}_{3}}-cyt\text{ }a,\text{ }cyt\text{ }c,\text{ }cyt\text{ }b\]

    Correct Answer: D

    Solution :

    The order of occurrence of the cytochromes in the F1 particle present in mitochondrial cristae is\[cyt\text{ }b,\text{ }cyt\text{ }c,\text{ }cyt\text{ }a-cyt-{{a}_{3}}.\] They accept electron and pass on to the other cytochrome, \[cyt{{a}_{3}}\]is oxido reductive cytochrome. s
