Twice
The Krebs cycle runs twice to break down one molecule of glucose.
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.
A single glucose molecule is able to drive the Krebs cycle 2 times. The Krebs Cycle is the series of chemical reactions that take place to provide all aerobic organisms with the ability to make energy.
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.
For each molecule of glucose consumed, the Krebs cycle (also known as the citric acid cycle) occurs twice. This is because one glucose molecule is broken down into two molecules of pyruvate during glycolysis, and each pyruvate is then converted into acetyl-CoA, which enters the Krebs cycle. Thus, for every glucose molecule, the cycle runs twice, producing energy carriers such as NADH and FADH2.
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 runs twice to break down one molecule of glucose.
For the complete respiration of one molecule of glucose, the citric acid cycle (Krebs cycle) operates twice. This is because one glucose molecule is broken down into two pyruvate molecules during glycolysis, and each pyruvate enters the citric acid cycle once. Therefore, the cycle earns a total of two turns for the complete oxidation of one glucose molecule.
six
The Calvin cycle needs to be run through six times to produce one molecule of glucose. This is because each turn of the Calvin cycle fixes one molecule of carbon dioxide, and glucose has six carbons in its structure.
