How much ATP is produced in the Krebs cycle?

How is ATP made in the Krebs cycle?

The Krebs cycle in eukaryotes uses a molecule acetyl CoA for 1 ATP, 3 NADHs, 1 FADH2, 1 FADH2, 1 CO2, and 3H+. The Krebs cycle produces NADH and FADH2 molecules that are then sent to the electron transport chain. This is the final stage of cellular respiration.

You should also know how much ATP is produced at each stage of cellular respiration. The electron transport chain can produce 32 to 34 ATP depending on the number of NADH molecules available. This 32-34 ATP can be combined with 2 ATP of glycolysis and 2 ATP of the Krebs cycle to make a total 36-38 ATP.

How is 36 ATP made?

In three stages, cellular respiration creates 36 total ATP for each glucose molecule. Energy is created by breaking the bonds between the carbons of the glucose molecule. Two NADH (electron carriers), which are high-energy electrons, can also be captured. These electrons will later be used in the electron transport chain.

What is the ATP used in the electron transport chain?

These two ATP molecules account for approximately one-third of the total. There are 32 ATP molecules generated by electron transport and oxidative phosphorylation.
