Question

Kreb's cycle is also known as citric cycle

Answer 1

After a long series of 10 reactions called glycolysis where 1 molecule of glucose is converted to 2 molecules of pyruvic acid, there is an intermediate reaction called the Link reaction where pyruvic acid gets converted to Acetyl-CoA. This Acetyl-CoA which enters the Kreb’s cycle is then further converted to the first stable product of the Kreb’s cycle which is called citric acid(citrate) in the presence of an enzyme called citrate synthase. Due to this very reason, the Kreb’s cycle is called the citric acid cycle or tri-carboxylic acid cycle because if you look at the structure of citric acid closely, you will notice that it has 3 carboxylic acid groups. Hence the name.

Answer 2

Hi..
The Krebs cycle, which is also known as the citric acid cycle or tricarboxylic acid cycle, is part of a series of chemical reactions that organisms use to break food down into a form of energy that cells can use. The cycle occurs in mitochondria of cells, using 2 molecules of pyruvic acid from glycolysis to produce the energy molecules. The Krebs cycle forms (per two molecules of pyruvic acid) 2 ATP molecules, 10 NADH molecules, and 2 FADH2 molecules..

Hope this helps u!!
