At the end of the Krebs cycle, four carbon compounds that are regenerated include oxaloacetate, which is essential for the cycle to continue, citrate, isocitrate, and alpha-ketoglutarate. These compounds are continually recycled to keep the cycle running efficiently.
Oxaloacetate combines with Acetyl CoA to actually start the Krebs Cycle. Oxaloacetate is regenerated at the end of the cycle as well.

Why is the 4-carbon compound generated in the breakdown of citric acid the only permanent compound in the Krebs 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.
What is the molecule that is regenerated with every turn of the Krebs cycle?
Each turn of the Kreb's cycle must regenerate oxaloacetate.
During what cycle do a series of reactions occur in the mitochondria which release carbon dioxide?
Citric acid cycle
What cycle breaks down pyruvic acid into carbon dioxide and produces nadh fadh2 and atp?
The citric acid cycle, also known as the Krebs cycle, breaks down pyruvic acid into carbon dioxide and produces NADH, FADH2, and ATP. This cycle takes place in the mitochondria of eukaryotic cells and is an essential part of cellular respiration.
Why is the citric acid cycle a cyclic pathway rather than a linear pathway?
The citric acid cycle is a cyclic pathway because the end product, oxaloacetate, is regenerated at the end of the cycle to start again, allowing the pathway to continue repeatedly. This cycle of reactions facilitates the complete oxidation of acetyl-CoA to produce energy in the form of ATP.
Why is the 4-carbon compound generated in the breakdown of citric acid the only permanent compound in the Krebs 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.
Which substrate is regenerated after one cycle of the Kreb's cycle?
Oxaloacetate is the substrate that is regenerated after one cycle of the Krebs cycle. It combines with acetyl-CoA to continue the cycle.
What are the similarities between the Krebs Cycle and the Calvin cycle?
Similarity: They are both cycles, therefore both have a reactant that s regenerated. In the Krebs Cycle, oxaloacetate is regenerated. In the Calvin cycle, RuBP is regenerated (ribulose 1, 5-bisphosphate). Difference: Glucose is completely broken down in the Krebs Cycle to carbon dioxide, which in the Calvin Cycle, glucose is made as a product.
What molecule is regenerated in the Calvin cycle?
Carbon dioxide
Which compounds involved in the urea cycle are linked to the Krebs cycle?
Fumarate and aspartate are the compounds that are linked between the urea cycle and the Krebs cycle. Fumarate from the Krebs cycle can be converted to arginine in the urea cycle, while aspartate from the urea cycle can be converted to oxaloacetate in the Krebs cycle.
Which of the following compounds is regenerated in the citric acid cycle?
Oxaloacetate
In the Krebs cycle acetate combines with what 4-carbon compound?
oxaloacetic acid
What correctly matches a product of cellular respiration with the stage in which it forms?
carbon dioxide and the Krebs cycle
What is the waste product form during the Krebs cycle?
A byproduct of the krebs cycle/citric acid cycle is carbon dioxide.
What is the molecule that is regenerated with every turn of the Krebs cycle?
Each turn of the Kreb's cycle must regenerate oxaloacetate.
What gas is in the Krebs cycle?
Carbon dioxide (CO2) is a byproduct of the Krebs cycle. It is produced during the decarboxylation reactions that occur within the cycle, where carbon atoms are removed from molecules like citric acid.
What are the substrate of Krebs cycle?
NAD+, and Acetyl CoA.
