Step-by-step solution
Citric Cycle commonly known as TCA Cycle or Krebs' Cycle. This cycle is a part of aerobic respiration. In TCA Cycle, acetyl group gets condensed to produce citric acid with the presence of oxaloaceetic acid and water. Citric acid thus formed with the help of enzyme citrate synthase isomerization takes place and further by decarboxylation leads to formation of alpha-ketoglutaric acid and succinyl-CoA. During the synthesis of succinic acid from succinyl-CoA there is synthesis of Guanosine triphosphate (GTP).
