Citric Acid
One molecule of glucose is broken down into two molecules of pyruvate during glycolysis. Each pyruvate molecule then enters the Krebs cycle and is fully oxidized to produce three molecules of carbon dioxide. Therefore, in total, six molecules of carbon dioxide are produced when the Krebs cycle operates once.
It is true that the compound that joins with a 4-carbon molecule in the krebs cycle is called acetyl-CoA. It is also known as Acetyl coenzyme A.
The molecule you are referring to is NAD+ (nicotinamide adenine dinucleotide). It acts as a coenzyme electron carrier in the Krebs cycle by accepting and donating electrons during the oxidation-reduction reactions that occur in the 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.
The complete breakdown of one molecule of pyruvic acid is called the citric acid cycle, also known as the Krebs cycle. This process occurs in the mitochondria and results in the production of ATP, CO2, and high-energy electrons.
The Krebs cycle runs twice for each molecule of glucose consumed.
In a complete Krebs Cycle, 24 ATP are produced. Every glucose molecule produces 2 ATP, and there are 12 glucose molecules.
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.
The Krebs cycle produces a total of 2 ATP molecules per glucose molecule.

The Krebs cycle generates 1 ATP molecule per turn through substrate-level phosphorylation. Due to the cycle occurring twice per glucose molecule, a total of 2 ATP molecules are produced per glucose molecule entering the cycle.
The Krebs cycle produces 1 ATP molecule per cycle through substrate-level phosphorylation. Since the cycle completes twice for each glucose molecule entering glycolysis, a total of 2 ATP molecules are generated from the Krebs cycle per glucose molecule metabolized.
In the Krebs cycle, a total of 3 molecules of NADH are produced.
