In the Krebs cycle, also known as the citric acid cycle, carbon dioxide (CO2) is produced during the decarboxylation reactions that occur at specific steps in the cycle. Specifically, CO2 is released when isocitrate is converted to alpha-ketoglutarate and when alpha-ketoglutarate is converted to succinyl-CoA. These steps involve the removal of carbon atoms from the organic molecules, resulting in the release of CO2 as a byproduct. This process is essential for cellular respiration, as it helps to oxidize substrates to generate energy.
What else can I help you with?
What is end product of Krebs cycle?
CO2 (Carbon Dioxide) molecules are given off as waste gas in the Krebs cycle.
Where does co2 come from during Krebs cycle?
CO2 is produced during the Krebs cycle as a byproduct of decarboxylation reactions that occur when citrate is converted to isocitrate, isocitrate to alpha-ketoglutarate, and alpha-ketoglutarate to succinyl-CoA. These decarboxylation reactions release carbon dioxide as a waste product.
What stage of cell respiration produces the most co2?
the Krebs cycle, also called the citric acid cycle
During the energy extraction part of the Krebs cycle how many molecules of CO2 are released?
Two molecules of carbon dioxide are released during the energy extraction part of the Krebs cycle from each round of the citric acid cycle.
How many cycle after Krebs reaction one glucose molecule has been broken down to CO2?
One glucose molecule undergoes glycolysis, which breaks it down into two molecules of pyruvate. Each pyruvate then enters the Krebs cycle (or citric acid cycle), where it is fully oxidized. Since each glucose results in two pyruvate molecules, two cycles of the Krebs cycle occur per glucose molecule, leading to the production of CO2 as a byproduct in each cycle. Therefore, a total of six CO2 molecules are generated from one glucose molecule after two Krebs cycles.
Where did the first carbon come from in the Krebs cycle?
If by "first carbon" you mean the first CO2 released in the cycle then the answer is, from OAA. NOT from acetyl CoA.
What is end product of Krebs cycle?
CO2 (Carbon Dioxide) molecules are given off as waste gas in the Krebs cycle.
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.
Where does co2 come from during Krebs cycle?
CO2 is produced during the Krebs cycle as a byproduct of decarboxylation reactions that occur when citrate is converted to isocitrate, isocitrate to alpha-ketoglutarate, and alpha-ketoglutarate to succinyl-CoA. These decarboxylation reactions release carbon dioxide as a waste product.
How many molecules of CO2 are released during the Krebs cycle?
For every molecule of pyruvate entering the Krebs cycle, 3 molecules of CO2 are released. Since each glucose molecule produces 2 molecules of pyruvate through glycolysis, the total number of CO2 molecules released per glucose molecule in the Krebs cycle is 6.
What two of the products of the Krebs cycle?
CO2, NADH/H+, FADH2, ATP.
How many CO2 molecules are produced by the Krebs Cycle for a molecule of glucose?
4
What is made from the Kreb's cycle?
CO2, NADH, FADH2 are produced by the Krebs Cycle. Be sure you understand why and how that fits into your question.
What stage of cell respiration produces the most co2?
the Krebs cycle, also called the citric acid cycle
How many carbon dioxide molecules are produced in the Krebs cycle?
two :]
During the energy extraction part of the Krebs cycle how many molecules of CO2 are released?
Two molecules of carbon dioxide are released during the energy extraction part of the Krebs cycle from each round of the citric acid cycle.
In anaerobic respiration what steps produce carbon dioxide?
It's called the Krebs's cycle and it consists of the steps to convert a 2 carbon sugar into CO2 and H2O. (And you don't own the genetic code to do this ... only the mitochondria do.)
