Oxaloacetate
Each turn of the Kreb's cycle must regenerate oxaloacetate.
Oxaloacetate
Oxaloacetate is regenerated at the end of the cycle.
This 4-carbon molecule is then ready to accept another 2-carbon acetyl group, which starts the cycle all over again.It is regenerated at the end of each complete turn of the cycle.
Carbon dioxide
The citric acid cycle is a cyclic pathway rather than a linear pathway because it is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms that form a two-carbon compound such as acetyl CoA.
The citric acid cycle (Krebs cycle) produces energy in the form of ATP. It plays a central role in the metabolism of carbohydrates, fats, and proteins. It provides precursor molecules for the synthesis of various important compounds, such as amino acids and nucleotides.
C6 cycle, Citric/Citric Acid cycle
Pyruvic acid is converted into acetyl CoA before it enters the citric acid cycle. Acetyl CoA combines with oxaloacetate to form citrate, initiating the citric acid cycle. This cycle is essential for extracting energy from carbohydrates through a series of redox reactions.
