Question

Under which condition is pyruvic acid formed?

Answer 1

Pyruvic acid

1. Pyruvic acid is the 2-keto derivative of propionic acid and is a 2-oxo monocarboxylic acid.
2. It's a metabolite produced by glycolysis.
3. The process by which glucose is broken down to provide energy is known as glycolysis.
4. It produces water, ATP, NADH, and two pyruvate molecules.
5. There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
6. Pyruvic acid can be made from glucose through glycolysis, converted back to carbohydrates (such as glucose) via gluconeogenesis, or to fatty acids through a reaction with acetyl-CoA.
7. It can also be used to construct the amino acid alanine and can be converted into ethanol or lactic acid via fermentation.
8. During the glycolysis process, glucose is changed into pyruvate.
9. Phosphoglycerate kinase and pyruvate kinase catalyze events that result in the synthesis of ATP.
10. These reactions are indicated in yellow and are instances of substrate-level phosphorylation.
11. Two molecules of pyruvate are the last products of glycolysis in cellular respiration, two ATP molecules, and two NADH molecules.
12. Pyruvic acid is produced in the presence of oxygen in the body.
