Biological Classification
  1. In Krebs cycle FAD participates as electron acceptor during the conversion of
    1. succinyl CoA to Succinic acid
    2. alfa keto glutarate to Succinyl CoA
    3. succinic acid to Fumaric acid
    4. fumaric acid to Malic acid
Correct Option: C

In the conversion of succinyl Co A to succinic acid, energy liberated during hydrolysis of succinyl CoA is used in synthesis of GTP. For the conversion of alfaketoglutarate to succinyl CoA, NAD+ and CoA are required. Conversion of fumaric acid to malic acid involves simple hydration. FAD participates in conversion of succinic acid to fumaric acid.
