Two carbons from one glucose molecule enter one round of the Krebs cycle in the form of acetyl-CoA, which is derived from pyruvate through pyruvate dehydrogenase.

In a complete Krebs Cycle, 24 ATP are produced. Every glucose molecule produces 2 ATP, and there are 12 glucose molecules.
There are four carbons in a molecule of malate at the end of the Krebs cycle.
The Krebs cycle produces a total of 2 ATP molecules per glucose molecule.

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.

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.
The Krebs cycle (or citric acid cycle) runs twice for each molecule of glucose that is broken down. This is because one glucose molecule is converted into two molecules of pyruvate during glycolysis, and each pyruvate then enters the Krebs cycle. Thus, for every glucose molecule, the Krebs cycle processes two acetyl-CoA molecules, resulting in two turns of the cycle.
The Krebs cycle runs twice for each molecule of glucose consumed.
During the Krebs cycle, one molecule of water (H2O) is produced for each round of the cycle. At the end of the cycle, a total of two molecules of water per molecule of glucose are generated.
