In krebs cycle which step aldol condensation of process walker
Answers
The situation changed with the discovery of a non-enzymatic glycolysis and pentose phosphate pathway.
The suite of metabolism-like reactions is promoted by a metal cation, (Fe(II)), abundant in Archean sediment, and requires no condition step changes.
Knowledge about metabolism-like reaction topologies has accumulated since, and supports non-enzymatic origins of gluconeogenesis, the S-adenosylmethionine pathway, the Krebs cycle, as well as CO2 fixation.

Explanation:
The Krebs cycle is also called tricarboxylic acid (TCA) cycle or the citric acid cycle. It takes place in the matrix of the mitochondria.
The cycle starts with the reaction between acetyl-CoA and the four-carbon oxaloacetate to form six-carbon citric acid. Through the next steps of the cycle, two of the six carbons of the citric acid removed as carbon dioxide (CO2) to yield the four-carbon compound, oxaloacetate, which is used again in the first step of the next cycle. During the eight reactions that take place, for every molecule of acetyl-CoA the cycle produces three NADH and one flavin adenine dinucleotide (FAD/FADH2), along with one molecule of ATP.
The net equation of the Krebs cycle:
Acetyl CoA + 3 NAD + FAD + ADP + HPO4-2 ——> 2 CO2 + CoA + 3NADH+ + FADH+ + ATP
