NAD+, and Acetyl CoA.
Oxaloacetate is regenerated at the end of the cycle.
Other substrates that can enter the Krebs cycle include fatty acids from fat metabolism and amino acids from protein metabolism. These substrates are converted into intermediates that can feed into the Krebs cycle at various points.
when oxygen is not present
The major message of the Krebs cycle for cell energetics is that it generates ATP with substrate level phosphorylation.
Hans Krebs discovered the Krebs cycle, also known as the citric acid cycle, in 1937.
Oxaloacetate is regenerated at the end of the cycle.
ATP is formed by substrate-level phosphorylation during glycolysis and the Krebs cycle in cellular respiration. In both processes, a phosphate group is transferred from a substrate molecule directly to ADP to form ATP.

when oxygen is not present
The major message of the Krebs cycle for cell energetics is that it generates ATP with substrate level phosphorylation.
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.
Most of the ATP in the Krebs cycle is generated through substrate-level phosphorylation, where high-energy phosphate groups are transferred directly to ADP from phosphorylated intermediates in the cycle. This occurs in the reactions where GTP or ATP are produced.

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.
