Dear student.

Your question is not clear. Please recheck it and do get back to us.

Kreb;s cycle is known as tricarboxylic acid cycle because of the first product, citric acid which contains 3 carboxyl (COOH) groups.

Apart from this, the carboxylic containing group is citric acid, succinic acid, Oxaloacetate.

Krebs Hansleit Cycle is also called Ornithyine cycle or Urea Cyle.
The major role is played by 3 carboxylic / amino acids which are as follows :
  • Ornithine
  • Sitrulline
  • Arginin
​​These all are non-protein amino acids.
Hope this helps..

Kindly note you used the word only Kreb , which is absolutely wrong . Anyone can get confused in this.
Note : If u write only Krebs cycle then it can even mean to someone ...kreb cycle in mitochondria which do not require those acids (aerobic respiration).
so u must completely write the whole name i.e Krebs Hansleit  to make ur question clear.
