    B) ATP

    C)                                                                             \[{{H}_{2}}O\]

    D)                                                              \[FA{{D}^{+}}orFAD{{H}_{2}}\]

    Correct Answer: B

    Solution :

    [B] Pathway A is glycolysis, pathways is the krebs' cycle and pathway C is oxidative phosphorylation Arrow 1 —ADP or NAD+ Arrow 2 — Pyruvate Arrow 3 — NADH Arrow 4 — ATP Arrow 5 — ADP, NAD+ or FAD Arrow 6 and 7 — FADH2 and NADH (either one can be 6 or 7) Arrow 8 — ATP or CO2 Arrow 9 and 10 —O2 and ADP (either one can be 9 or 10) Arrow 11 and 12 — H2O and ATP (either one can be 11 or 12)
