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.
During what cycle do a series of reactions occur in the mitochondria which release carbon dioxide?
Citric acid cycle
What is a series of reactions in aerobic respiration that begins and ends with same 6-carbon compound is the?
The Krebs Cycle
What cycle breaks down pyruvic acid into carbon dioxide and produces nadh fadh2 and atp?
The citric acid cycle a.k.a. the tricarboxylic acid cycle , the Krebs cycle, or the Szent-Györgyi-Krebs cycle
The Kreb cycle starts with what?
The Krebs cycle starts with acetyl CoA, and combines with oxaloacetate to form citrate, a six-carbon molecule. Citrate is further oxidized until oxaloacetate is again reached at the end to restart the Krebs 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

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 of the following compounds is regenerated in the citric acid cycle?
Oxaloacetate
What is the main features of the Krebs cycle?
The Krebs cycle occurs in the matrix of the mitochondrion. It occurs only in aerobic conditions, that is, only when oxygen is present. Its main function is to oxidise acetyl CoA generated from glycolysis. In the Krebs cycle, acetyl CoA and oxaloacetate undergo a condensation reaction to form a six-carbon compound. Through a series of decarboxylation and dehydrogenation reactions, intermediate 5-carbon and 4-carbon compounds are formed with the release of carbon dioxide. 1 ATP molecule is generated per turn of the Krebs cycle by substrate level phosphorylation; hence 2 ATP molecules are formed per molecule of glucose. Most fo the chemical energy is transferred during the redox reactions where the electron carriers NAD and FAD are reduced to form coenzymes NADH and FADH2, respectively. The Krebs cycle is also cyclic as the starting product, oxaloacetate, is regenerated.
Which compounds involved in the urea cycle are linked to the Krebs cycle?
fumarate
What correctly matches a product of cellular respiration with the stage in which it forms?
carbon dioxide and the Krebs cycle
In the Krebs cycle acetate combines with what 4-carbon compound?
oxaloacetic acid
What gas is in the Krebs cycle?
The gas evolved during the Krebs cycle is carbon dioxide (CO2).
What is the waste product form during the Krebs cycle?
A byproduct of the krebs cycle/citric acid cycle is carbon dioxide.
What are the components of the Krebs Cycle?
carbon dioxide
During what cycle do a series of reactions occur in the mitochondria which release carbon dioxide?
Citric acid cycle
