Oxaloacetate is regenerated at the end of the cycle.
when oxygen is not present
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 NAD+ is reduced to NADH. This is one of the electron carriers. Also FAD is reduced to FADH2 which is the other electron carrier produced during the Krebs cycle.
The Krebs cycle, also known as the citric acid cycle, must run once for each molecule of pyruvate. Since one glucose molecule produces two pyruvate molecules during glycolysis, the Krebs cycle runs twice for each glucose molecule. Therefore, for one molecule of pyruvate, the cycle runs just once.
The Krebs cycle, also known as the citric acid cycle or TCA cycle, occurs twice for each molecule of glucose that is metabolized. This is because one glucose molecule is broken down into two pyruvate molecules during glycolysis, and each pyruvate enters the Krebs cycle individually. Therefore, for every glucose molecule, the Krebs cycle completes two full turns.
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.
Each turn of the Kreb's cycle must regenerate oxaloacetate.

FADH2 since pyruvic acid is needed to START the Krebs cycle
In the Krebs cycle NAD+ is reduced to NADH. This is one of the electron carriers. Also FAD is reduced to FADH2 which is the other electron carrier produced during the Krebs cycle.
The Krebs cycle runs twice to break down one molecule of glucose.
One molecule of ATP is typically produced during substrate-level phosphorylation. This occurs when a high-energy phosphate group is transferred directly from a substrate molecule to ADP, forming ATP.
The Krebs cycle, also known as the citric acid cycle, must run once for each molecule of pyruvate. Since one glucose molecule produces two pyruvate molecules during glycolysis, the Krebs cycle runs twice for each glucose molecule. Therefore, for one molecule of pyruvate, the cycle runs just once.
The Krebs cycle, also known as the citric acid cycle or TCA cycle, occurs twice for each molecule of glucose that is metabolized.

Therefore, for every glucose molecule, the Krebs cycle completes two full turns.
The energy tally from one molecule of pyruvic acid is 4 NADH, 1 FADH₂ and 1 molecule of ATP.
