Question

In Krebs cycle, guanosine triphosphate is formed during the conversion of

• A. Isocitrate to otalosuccinate
• B. Oxalosuccinate to -ketoglutarate
• C. Succinyl CoA to succinate
• D. Fumarate to malate

Answer 1

Answer: (C)

Succinyl CoA to succinate

In the seventh step, Krebs cycle in which Succinyl CoA is converted into Succinic acid by the action of enzyme Succinic thiokinase in which release of energy takes lace and GDP converts into GTP in which one ATP is released.

So, the correct option is 'Succinyl CoA to succinate'.
