Tricarboxylic acid cycle the cyclic metabolic mechanism by which the complete oxidation of the acetyl portion of acetyl-coenzyme A is effected; the process is the chief source of mammalian energy, during which carbon chains of sugars, fatty acids, and amino acids are metabolized to yield carbon dioxide, water, and high-energy phosphate bonds.

HI!!
HERE IZ UR ANSWER.
Kreb's Cycle is also known as Tricarboxylic acid because first stabe product of Krebs Cycle is Citric acid which contain 3 carboxylic acid group (COOH).
It is also known as citric acid cycle for the same reason.
In a Krebs cycle,
Total 30 ATPs are formed.
As for one mol. of Pyruvate, Kreb Cycle includes
Dehydrogenation steps where NADH2 is released = 4
Substrate level Phosphorylation = 1 step
No. of step where FADH2 is released = 1.
And,
1 NADH2 = 3 ATPs
so, 4 NADH2 = 12 ATPs
+
1 FADH2 = 2 ATPs
+
Substrate level Phosphorylation = 1 ATP
so total ATP in Kreb cycle for one mol. of Pyruvate is 15 ATPs.
and for 2 molecules, it is 30 ATPs.
HOPE IT HELPS!!
