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!!
