Respiration in Plants Question 44
44. In Krebs cycle FAD participates as electron acceptor during the conversion of
(a) succinyl CoA to Succinic acid
(b) alfa keto glutarate to Succinyl CoA
(c) succinic acid to Fumaric acid
(d) fumaric acid to Malic acid
Show Answer
Answer : c
Hints & Solutions
(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 alfa-ketoglutarate 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.
