Which of the following organic acid is the substrate for the step in which GTP is formed during Kreb's cycle.?

Step-by-step solution

Kreb's cycle / TCA cycle: Discovery: This cycle has been named after Sir Hans Kreb, the German biochemist who discovered this cycle in 1937. Kreb's cycle is also known as the citric acid cycle as it is the first stable product of the cycle. This cycle takes place in the matrix of mitochondria as it has a presence of various soluble enzymes here. Like glycolysis, it also involves 10 sequential steps in which the cycle is completed. The sequential steps of the Kreb cycle are as follows: (i) Condensation reaction: A 2
