if you're talking about after the carbons are exhaled through CO2 the the pyruvate need to give off more CO2 for it to be Acetyl Co-A to pass through the mitochondrial membrane to go through the Krebs cycle. so in the Krebs cycle it's acetyl Co-A. Then it goes to the electron transport chain.

What does the Krebs make?

During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2.


What happens during Krebs cycle?

Does pyruvic acid enters the krebs cycle?

Pyruvic acid cycle does enter the Krebs cycle and is turned into acetyl coenzyme A.


Which one is formed during the Krebs cycle FADH2 or pyruvic acid?

FADH2 since pyruvic acid is needed to START the Krebs cycle


How is pyruvic acid used in the Kreb's cycle?

Pyruvic acid is first converted to acetyl-CoA before entering the Krebs cycle. Acetyl-CoA combines with oxaloacetate to form citric acid, which initiates the Krebs cycle. Throughout the cycle, acetyl-CoA is oxidized to produce energy in the form of ATP, NADH, and FADH2.


Can pyruvic acid use in the Krebs cycle?

The pyruvic acid that is produced by glycolysis is used as the initial input for the Krebs Cycle (also called citric acid cycle). In the initial step of the Krebs Cycle, the pyruvic acid is converted to acetyl-CoA via pyruvate decarboxylation. This continues a series of chemical reactions leading to the production of 2 ATP molecules.


What purpose does pyruvic acid serve?

Pyruvic acid (or pyruvate) is simply one of the compounds in the metabolic pathway from sugars to carbon dioxide and water. From pyruvate (a three cabon unit) either one of two reactions can occur. It can react to form lactose or lose a carbon dioxide molecule to become a two carbon unit and enter the Krebs cycle.


What does Krebs cycle start with?

The answer is pyruvic acid no it's not, this failure up here ↑ is wrong, the answer is acetyl, then two carbon molecules enter the cycle


What does kreb cycle make?

During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2.
