    Last electron acceptor in respiration is

    A)  \[{{O}_{2}}\]             

    B)  \[{{H}_{2}}\]

    C)  \[C{{O}_{2}}\]            

    D)  NADH

    Correct Answer: A

    Solution :

     Electron transport chain takes place in inner mitochondrial membrane and consist of flavins, ubiquinone cytochromes and oxygen as electron carriers.    Sequence of electron transport: \[NAD{{H}_{2}}\xrightarrow[{}]{{}}FADCo-Q\xrightarrow[{}]{{}}\] Cytochrome\[b\xrightarrow[{}]{{}}Cyt-{{c}_{1}}\xrightarrow[{}]{{}}Cyt-a\]      \[\xrightarrow[{}]{{}}Cyt-{{a}_{3}}\xrightarrow[{}]{{}}{{O}_{2}}\] So, oxygen is the last electron acceptor in respiration.
